More fix for #24981

* #22361
There were many patches for Gitea's sub-commands to satisfy the facts:
* Some sub-commands shouldn't output any log, otherwise the git protocol
would be broken
* Sometimes the users want to see "verbose" or "quiet" outputs
That's a longstanding problem, and very fragile. This PR is only a quick
patch for the problem.
In the future, the sub-command system should be refactored to a clear
solution.
----
Other changes:
* Use `ReplaceAllWriters` to replace
`RemoveAllWriters().AddWriters(writer)`, then it's an atomic operation.
* Remove unnecessary `syncLevelInternal` calls, because
`AddWriters/addWritersInternal` already calls it.

A regression of #25330 : The nil "Action" should be treated as "help"
In old releases: `./gitea admin` show helps
After #25330: `./gitea admin` panics (although the code returned `nil`
if action is nil, but Golang's quirk is: nil in interface is not nil)
With this PR: `./gitea admin` shows helps as the old releases.
Fix#25481
The `InitWorkPathAndCommonConfig` calls `LoadCommonSettings` which does
many checks like "current user is root or not".
Some commands like "environment-to-ini" shouldn't do such check, because
it might be run with "root" user at the moment (eg: the docker's setup
script)
ps: in the future, the docker's setup script should be improved to avoid
Gitea's command running with "root"

In modern days, there is no reason to make users set "charset" anymore.
Close#25378
## ⚠️ BREAKING
The key `[database].CHARSET` was removed completely as every newer
(>10years) MySQL database supports `utf8mb4` already.
There is a (deliberately) undocumented new fallback option if anyone
still needs to use it, but we don't recommend using it as it simply
causes problems.
# The problem
There were many "path tricks":
* By default, Gitea uses its program directory as its work path
* Gitea tries to use the "work path" to guess its "custom path" and
"custom conf (app.ini)"
* Users might want to use other directories as work path
* The non-default work path should be passed to Gitea by GITEA_WORK_DIR
or "--work-path"
* But some Gitea processes are started without these values
* The "serv" process started by OpenSSH server
* The CLI sub-commands started by site admin
* The paths are guessed by SetCustomPathAndConf again and again
* The default values of "work path / custom path / custom conf" can be
changed when compiling
# The solution
* Use `InitWorkPathAndCommonConfig` to handle these path tricks, and use
test code to cover its behaviors.
* When Gitea's web server runs, write the WORK_PATH to "app.ini", this
value must be the most correct one, because if this value is not right,
users would find that the web UI doesn't work and then they should be
able to fix it.
* Then all other sub-commands can use the WORK_PATH in app.ini to
initialize their paths.
* By the way, when Gitea starts for git protocol, it shouldn't output
any log, otherwise the git protocol gets broken and client blocks
forever.
The "work path" priority is: WORK_PATH in app.ini > cmd arg --work-path
> env var GITEA_WORK_DIR > builtin default
The "app.ini" searching order is: cmd arg --config > cmd arg "work path
/ custom path" > env var "work path / custom path" > builtin default
## ⚠️ BREAKING
If your instance's "work path / custom path / custom conf" doesn't meet
the requirements (eg: work path must be absolute), Gitea will report a
fatal error and exit. You need to set these values according to the
error log.

That's a longstanding INI package problem: the "MustXxx" calls change
the option values, and the following "Save" will save a lot of garbage
options into the user's config file.
Ideally we should refactor the INI package to a clear solution, but it's
a huge work.
A clear workaround is what this PR does: when "Save", load a clear INI
instance and save it.
Partially fix#25377, the "install" page needs more fine tunes.

If the APP_DATA_PATH isn't written into the config when installing, then
its value is uncertain because some Gitea command doesn't run with
correct WorkPath.
This is a quick fix for #25330 and can be backported.
1. The "web" package shouldn't depends on "modules/context" package,
instead, let each "web context" register themselves to the "web"
package.
2. The old Init/Free doesn't make sense, so simplify it
* The ctx in "Init(ctx)" is never used, and shouldn't be used that way
* The "Free" is never called and shouldn't be called because the SSPI
instance is shared

Fixes: https://github.com/go-gitea/gitea/issues/25282
Fix the problems:
1. The `repo-button-row` had various patches before, this PR makes it
consistent
2. The "Add File" has wrong CSS class "icon", remove it
3. The "Add File" padding was overridden by "!important", fix it by
`.repo-button-row .button.dropdown` with comment
4. The selector `.ui.segments ~ .ui.top.attached.header` is incorrect,
it should use `+`
It causes not only one issue like #25221 (the footer width was also
affected by that change and was fixed some time ago)
The problem of "overflow: overlay" (#21850) is:
* It's not widely supported and is non-standard
https://caniuse.com/css-overflow-overlay
* It's not widely tested in Gitea (some standard layout like `ui
container + ui grid` may break it).
* The benefit seems smaller than the problems it brings.
So, I think it is good to revert it.

Clarify the "link-action" behavior:

"data-redirect" attribute, or current URL by reloading.
And enhance the "link-action" to support showing a modal dialog for
confirm. A similar general approach could also help PRs like

According to my test, the UI (emoji) is fine in Safari
And actually the code is just dead code, because the "resize" event is
never fired on page loading. So for most cases users just view the pages
without this hacky patch, nobody ever complains.
That ID is a "copy&paste" error, it conflicts with the
`initRepoMigrationStatusChecker` logic, which is the right function for
a real `#repo_migrating` element. That wrong ID causes incorrect page
navigation after installation.
Follow:
* #22697
There are some bugs in #22697:
* https://github.com/go-gitea/gitea/pull/22697#issuecomment-1577957966
* the webauthn failure message is never shown and causes console error
* The `document.getElementById('register-button')` and
`document.getElementById('login-button')` is wrong
* there is no such element in code
* it causes JS error when a browser doesn't provide webauthn
* the end user can't see the real error message
These bugs are fixed in this PR.
Other changes:
* Use simple HTML/CSS layouts, no need to use too many `gt-` patches
* Make the webauthn page have correct "page-content" layout
* The "data-webauthn-error-msg" elements are only used to provide locale
texts, so move them into a single "gt-hidden", then no need to repeat a
lot of "gt-hidden" in code
* The `{{.CsrfTokenHtml}}` is a no-op because there is no form
* Many `hideElem('#webauthn-error')` in code is no-op because the
`webauthn-error` already has "gt-hidden" by default
* Make the tests for "URLEncodedBase64" really test with concrete cases.

Before, Gitea shows the database table stats on the `admin dashboard`
page.
It has some problems:
* `count(*)` is quite heavy. If tables have many records, this blocks
loading the admin page blocks for a long time
* Some users had even reported issues that they can't visit their admin
page because this page causes blocking or `50x error (reverse proxy
timeout)`
* The `actions` stat is not useful. The table is simply too large. Does
it really matter if it contains 1,000,000 rows or 9,999,999 rows?
* The translation `admin.dashboard.statistic_info` is difficult to
maintain.
So, this PR uses a separate page to show the stats and removes the
`actions` stat.
## ⚠️ BREAKING
The `actions` Prometheus metrics collector has been removed for the
reasons mentioned beforehand.
Please do not rely on its output anymore.
The INI package has many bugs and quirks, and in fact it is
unmaintained.
This PR is the first step for the INI package refactoring:
* Use Gitea's "config_provider" to provide INI access
* Deprecate the INI package by golangci.yml rule
The admin config page has been broken for many many times, a little
refactoring would make this page panic.
So, add a test for it, and add another test to cover the 500 error page.

gitea.com experienced the corrupted LevelQueue bug again.
I think the problem is clear now: if the keys in LevelDB went
out-of-sync, the LevelQueue itself doesn't have the ability to recover,
eg:
* LevelQueue.Len() reports 100
* LevelQueue.LPop() reports ErrNotFound = errors.New("no key found")
So it needs to dive into the LevelDB to remove all keys to recover the
corrupted LevelQueue.
More comments are in TestCorruptedLevelQueue.
The old EventWriter's Run does:
```go
for {
handlePause()
select {
case event <- Queue:
write the log event ...
}
}
```
So, if an event writer is started before the logger is paused, there is
a chance that the logger isn't paused for the first message.
The new logic is:
```go
for {
select {
case event <- Queue:
handlePause()
write the log event ...
}
}
```
Then the event writer can be correctly paused
The old process manager's `Trace` function by default calls `log.Printf`
to output "trace" level logs. That's not ideal because by default the
trace level logs should not be outputted. In history it didn't cause
problems because there was no other call to the process manager before
the logger system's initialization.
But if there is any package using the process manager before the "Trace"
function gets assigned to the logger system's trace function, the
process manager will outputs unexpected verbose messages, this behavior
is not expected in most cases.
Now, the logger system also uses process manager to manage its goroutine
contexts, so it's the time to fix the old "trace" behavior: by default,
do not output the trace level messages. Fix#24951
Before there was a "graceful function": RunWithShutdownFns, it's mainly
for some modules which doesn't support context.
The old queue system doesn't work well with context, so the old queues
need it.
After the queue refactoring, the new queue works with context well, so,
use Golang context as much as possible, the `RunWithShutdownFns` could
be removed (replaced by RunWithCancel for context cancel mechanism), the
related code could be simplified.
This PR also fixes some legacy queue-init problems, eg:
* typo : archiver: "unable to create codes indexer queue" => "unable to
create repo-archive queue"
* no nil check for failed queues, which causes unfriendly panic
After this PR, many goroutines could have better display name:
1. non-dev mode is treated as prod mode, to protect users from
accidentally running in dev mode if there is a typo in this value.
2. in dev mode, do not need to really exit if there are template errors,
because the template errors could be fixed by developer soon and the
templates get reloaded, help:

3. Fine tune the mail template loading message.

If users set different languages by `linguist-language`, the `stats` map

Many users have the requirement to customize the git config. This PR
introduces an easy way: put the options in Gitea's app.ini
`[git.config]`, then the config options will be applied to git config.
And it can support more flexible default config values, eg: now
`diff.algorithm=histogram` by default. According to:
https://stackoverflow.com/a/32367597/4754037 , `histogram diff` is
efficient and doesn't like to cause server-side problems.

## ⚠️ Breaking
The `log.<mode>.<logger>` style config has been dropped. If you used it,
please check the new config manual & app.example.ini to make your
instance output logs as expected.
Although many legacy options still work, it's encouraged to upgrade to
the new options.
The SMTP logger is deleted because SMTP is not suitable to collect logs.
If you have manually configured Gitea log options, please confirm the
logger system works as expected after upgrading.
## Description
Close#12082 and maybe more log-related issues, resolve some related
FIXMEs in old code (which seems unfixable before)
Just like rewriting queue #24505 : make code maintainable, clear legacy
bugs, and add the ability to support more writers (eg: JSON, structured
log)
There is a new document (with examples): `logging-config.en-us.md`
This PR is safer than the queue rewriting, because it's just for
logging, it won't break other logic.
## The old problems
The logging system is quite old and difficult to maintain:
* Unclear concepts: Logger, NamedLogger, MultiChannelledLogger,
SubLogger, EventLogger, WriterLogger etc
* Some code is diffuclt to konw whether it is right:
`log.DelNamedLogger("console")` vs `log.DelNamedLogger(log.DEFAULT)` vs
`log.DelLogger("console")`
* The old system heavily depends on ini config system, it's difficult to
create new logger for different purpose, and it's very fragile.
* The "color" trick is difficult to use and read, many colors are
unnecessary, and in the future structured log could help
* It's difficult to add other log formats, eg: JSON format
* The log outputer doesn't have full control of its goroutine, it's
difficult to make outputer have advanced behaviors
* The logs could be lost in some cases: eg: no Fatal error when using
CLI.
* Config options are passed by JSON, which is quite fragile.
* INI package makes the KEY in `[log]` section visible in `[log.sub1]`
and `[log.sub1.subA]`, this behavior is quite fragile and would cause
more unclear problems, and there is no strong requirement to support
`log.<mode>.<logger>` syntax.
## The new design
See `logger.go` for documents.

Mixing different Gitea contexts together causes some problems:
1. Unable to respond proper content when error occurs, eg: Web should

2. Unclear dependency, eg: it's unclear when Context is used in
APIContext, which fields should be initialized, which methods are
necessary.
To make things clear, this PR introduces a Base context, it only
provides basic Req/Resp/Data features.
This PR mainly moves code. There are still many legacy problems and

`http.ServeFile/ServeContent` handles `If-xxx`, `Content-Length`,
`Range` and `Etag` correctly
After this PR, storage files (eg: avatar) could be responded with
correct Content-Length.
Although some features are mixed together in this PR, this PR is not
that large, and these features are all related.
Actually there are more than 70 lines are for a toy "test queue", so
this PR is quite simple.
Major features:
1. Allow site admin to clear a queue (remove all items in a queue)
* Because there is no transaction, the "unique queue" could be corrupted
in rare cases, that's unfixable.
* eg: the item is in the "set" but not in the "list", so the item would
never be able to be pushed into the queue.
* Now site admin could simply clear the queue, then everything becomes
correct, the lost items could be re-pushed into queue by future
operations.
3. Split the "admin/monitor" to separate pages
4. Allow to download diagnosis report
* In history, there were many users reporting that Gitea queue gets
stuck, or Gitea's CPU is 100%
* With diagnosis report, maintainers could know what happens clearly
The diagnosis report sample:
[gitea-diagnosis-20230510-192913.zip](https://github.com/go-gitea/gitea/files/11441346/gitea-diagnosis-20230510-192913.zip)

According to the discussion with DanielGibson, the default "20m" seems
too short. It would make LFS fail if the file is large / network is
slow.
I think relaxing this timeout doesn't have side affect. So change the
default value to 24h, IMO that should be long enough.
## ⚠️ BREAKING
If admins want the previous timeout, they should set the setting
`[server].LFS_HTTP_AUTH_EXPIRY`.

# ⚠️ Breaking
Many deprecated queue config options are removed (actually, they should
have been removed in 1.18/1.19).
If you see the fatal message when starting Gitea: "Please update your
app.ini to remove deprecated config options", please follow the error
messages to remove these options from your app.ini.
Example:
```
2023/05/06 19:39:22 [E] Removed queue option: `[indexer].ISSUE_INDEXER_QUEUE_TYPE`. Use new options in `[queue.issue_indexer]`
2023/05/06 19:39:22 [E] Removed queue option: `[indexer].UPDATE_BUFFER_LEN`. Use new options in `[queue.issue_indexer]`
2023/05/06 19:39:22 [F] Please update your app.ini to remove deprecated config options
```
Many options in `[queue]` are are dropped, including:
`WRAP_IF_NECESSARY`, `MAX_ATTEMPTS`, `TIMEOUT`, `WORKERS`,
`BLOCK_TIMEOUT`, `BOOST_TIMEOUT`, `BOOST_WORKERS`, they can be removed
from app.ini.
# The problem
The old queue package has some legacy problems:
* complexity: I doubt few people could tell how it works.
* maintainability: Too many channels and mutex/cond are mixed together,
too many different structs/interfaces depends each other.
* stability: due to the complexity & maintainability, sometimes there
are strange bugs and difficult to debug, and some code doesn't have test
(indeed some code is difficult to test because a lot of things are mixed
together).
* general applicability: although it is called "queue", its behavior is
not a well-known queue.
* scalability: it doesn't seem easy to make it work with a cluster
without breaking its behaviors.
It came from some very old code to "avoid breaking", however, its
technical debt is too heavy now. It's a good time to introduce a better
"queue" package.
# The new queue package
It keeps using old config and concept as much as possible.
* It only contains two major kinds of concepts:
* The "base queue": channel, levelqueue, redis
* They have the same abstraction, the same interface, and they are
tested by the same testing code.
* The "WokerPoolQueue", it uses the "base queue" to provide "worker
pool" function, calls the "handler" to process the data in the base
queue.
* The new code doesn't do "PushBack"
* Think about a queue with many workers, the "PushBack" can't guarantee
the order for re-queued unhandled items, so in new code it just does
"normal push"
* The new code doesn't do "pause/resume"
* The "pause/resume" was designed to handle some handler's failure: eg:
document indexer (elasticsearch) is down
* If a queue is paused for long time, either the producers blocks or the
new items are dropped.
* The new code doesn't do such "pause/resume" trick, it's not a common
queue's behavior and it doesn't help much.
* If there are unhandled items, the "push" function just blocks for a
few seconds and then re-queue them and retry.
* The new code doesn't do "worker booster"
* Gitea's queue's handlers are light functions, the cost is only the
go-routine, so it doesn't make sense to "boost" them.
* The new code only use "max worker number" to limit the concurrent
workers.
* The new "Push" never blocks forever
* Instead of creating more and more blocking goroutines, return an error
is more friendly to the server and to the end user.
There are more details in code comments: eg: the "Flush" problem, the
strange "code.index" hanging problem, the "immediate" queue problem.
Almost ready for review.
TODO:
* [x] add some necessary comments during review
* [x] add some more tests if necessary
* [x] update documents and config options
* [x] test max worker / active worker
* [x] re-run the CI tasks to see whether any test is flaky
* [x] improve the `handleOldLengthConfiguration` to provide more
friendly messages
* [x] fine tune default config values (eg: length?)
## Code coverage:
The "modules/context.go" is too large to maintain.
This PR splits it to separate files, eg: context_request.go,
context_response.go, context_serve.go
This PR will help:
1. The future refactoring for Gitea's web context (eg: simplify the context)
2. Introduce proper "range request" support
3. Introduce context function
This PR only moves code, doesn't change any logic.
Help some users like #16832#1851
There are many users reporting similar problem: if the SECRET_KEY
mismatches, some operations (like 2FA login) only reports unclear 500
error and unclear "base64 decode error" log （some maintainers ever spent
a lot of time on debugging such problem)
The SECRET_KEY was not well-designed and it is also a kind of technical
debt. Since it couldn't be fixed easily, it's good to add clearer error
messages, then at least users could know what the real problem is.

2. Move duplicate code from `Contexter` to `CommonTemplateContextData`
3. Remove incorrect copying&pasting code `ctx.Data["Err_Password"] =
true` in API handlers
4. Use one unique `RenderPanicErrorPage` for panic error page rendering
5. Move `stripSlashesMiddleware` to be the first middleware
6. Install global panic recovery handler, it works for both `install`
and `web`
7. Make `500.tmpl` only depend minimal template functions/variables,
avoid triggering new panics

I am not sure what "new-menu" means, but I think we need to fix these
problems:
1. it shouldn't have "stackable", which makes the items stacked when
width is small. the `new-menu` already has `overflow: auto`
2. `justify-content: center` doesn't work with `overflow: auto` (for
small width), so use `margin: auto`

3. `runner-new-menu` is dead code (copying & pasting ?)
Partial regression of #24393, not only regression, but broken for long
time, 24393 didn't really improve it but used wrong `overflow: scroll`.
Actually, that "ui secondary filter menu labels" shouldn't be set as
scrollable (I missed that at that time), the problem is: if a "ui menu"
has "dropdown" items, then it should not be scrollable. Otherwise the
dropdown menu can't be shown correctly.
And there are more problems:
* The "issue-filters" shouldn't be used anywhere else (copying&pasting
problem again ....)
* There is also an "issue-actions" container, it should also be fixed.
* There are similar problems on the milestone page.
* The old comment in code: "grid column" doesn't work well.
The major changes of this PR are: use "flex: 1" instead of "ui grid
column".
After this PR, not 100% perfect but much better than before.
The old `HTMLRender` is not ideal.
1. It shouldn't be initialized multiple times, it consumes a lot of
memory and is slow.
2. It shouldn't depend on short-lived requests, the `WatchLocalChanges`
needs a long-running context.
3. It doesn't make sense to use FuncsMap slice.
HTMLRender was designed to only work for GItea's specialized 400+
templates, so it's good to make it a global shared instance.
There was only one `IsRepositoryExist` function, it did: `has && isDir`
However it's not right, and it would cause 500 error when creating a new
repository if the dir exists.
Then, it was changed to `has || isDir`, it is still incorrect, it
affects the "adopt repo" logic.
To make the logic clear:
* IsRepositoryModelOrDirExist
* IsRepositoryModelExist
