This PR adds a middleware which sets a ContextUser (like GetUserByParams before) in a single place which can be used by other methods. For routes which represent a repo or org the respective middlewares set the field too.
Also fix a bug in modules/context/org.go during refactoring.

This code adds a simple endpoint to apply patches to repositories and
branches on gitea. This is then used along with the conflicting checking
code in #18004 to provide a basic implementation of cherry-pick revert.
Now because the buttons necessary for cherry-pick and revert have
required us to create a dropdown next to the Browse Source button
I've also implemented Create Branch and Create Tag operations.

Nodeinfo is a way to expose certain metadata about a server for use of discovery regarding functionality of its federation capabilities.
Two endpoints are required:
1. `/.well-known/nodeinfo` which informs client where it can find the location of the location of its metadata (including which version of the schema is used)
2. the endpoint which exposes the metadata in json format according to schema.
Notes:
* `openRegistrations` is a required field, but I propose to set to false as default in case someone writes a crawler to discover "open" gitea instances
* to limit data leakage I also propose to not include the `usage` field (note it is required so it should be included, but left as empty).

Since the move to Chi the number of stack frames has proliferated somewhat catastrophically and we're up to 96 frames with multiple tests of the url outside of a trie which is inefficient.
This PR reduces the number of stack frames by 6 through careful use of Route, moves Captcha into its own router so that it only fires on Captcha routes, similarly for avatars and repo-avatars.
The robots.txt, / and apple-touch-icon.png are moved out of requiring Contexter.
It moves access logger higher in the stack frame because there is no reason why it can't be higher.

Fix#14121, #14478.
The `AccessLog` middleware has to be after `Contexter` or `APIContexter` so that we can get `LoginUserName` if possible.
And also there is a **BREAK** change that it removed internal API access log.
Use [chi](https://github.com/go-chi/chi) instead of the forked [macaron](https://gitea.com/macaron/macaron). Since macaron and chi have conflicts with session share, this big PR becomes a have-to thing. According my previous idea, we can replace macaron step by step but I'm wrong. :( Below is a list of big changes on this PR.
- [x] Define `context.ResponseWriter` interface with an implementation `context.Response`.
- [x] Use chi instead of macaron, and also a customize `Route` to wrap chi so that the router usage is similar as before.
- [x] Create different routers for `web`, `api`, `internal` and `install` so that the codes will be more clear and no magic .
- [x] Use https://github.com/unrolled/render instead of macaron's internal render
- [x] Use https://github.com/NYTimes/gziphandler instead of https://gitea.com/macaron/gzip
- [x] Use https://gitea.com/go-chi/session which is a modified version of https://gitea.com/macaron/session and removed `nodb` support since it will not be maintained. **BREAK**
- [x] Use https://gitea.com/go-chi/captcha which is a modified version of https://gitea.com/macaron/captcha
- [x] Use https://gitea.com/go-chi/cache which is a modified version of https://gitea.com/macaron/cache
- [x] Use https://gitea.com/go-chi/binding which is a modified version of https://gitea.com/macaron/binding
- [x] Use https://github.com/go-chi/cors instead of https://gitea.com/macaron/cors
- [x] Dropped https://gitea.com/macaron/i18n and make a new one in `code.gitea.io/gitea/modules/translation`
- [x] Move validation form structs from `code.gitea.io/gitea/modules/auth` to `code.gitea.io/gitea/modules/forms` to avoid dependency cycle.
- [x] Removed macaron log service because it's not need any more. **BREAK**
- [x] All form structs have to be get by `web.GetForm(ctx)` in the route function but not as a function parameter on routes definition.
- [x] Move Git HTTP protocol implementation to use routers directly.
- [x] Fix the problem that chi routes don't support trailing slash but macaron did.
- [x] `/api/v1/swagger` now will be redirect to `/api/swagger` but not render directly so that `APIContext` will not create a html render.
Notices:
- Chi router don't support request with trailing slash
- Integration test `TestUserHeatmap` maybe mysql version related. It's failed on my macOS(mysql 5.7.29 installed via brew) but succeed on CI.

* Don't automatically delete repository files if they are present
Prior to this PR Gitea would delete any repository files if they are
present during creation or migration. This can in certain circumstances
lead to data-loss and is slightly unpleasant.
This PR provides a mechanism for Gitea to adopt repositories on creation
and otherwise requires an explicit flag for deletion.
PushCreate is slightly different - the create will cause adoption if
that is allowed otherwise it will delete the data if that is allowed.

Implement organization wide labels similar to organization wide

After much debugging I've found a strange issue where in some cases MySQL will return a different result than other enigines if a query is sorted by a null collumn. For example with our integration test data where we don't set updated_unix in repository fixtures:
SELECT `id`, `owner_id`, `owner_name`, `lower_name`, `name`, `description`, `website`, `original_service_type`, `original_url`, `default_branch`, `num_watches`, `num_stars`, `num_forks`, `num_issues`, `num_closed_issues`, `num_pulls`, `num_closed_pulls`, `num_milestones`, `num_closed_milestones`, `is_private`, `is_empty`, `is_archived`, `is_mirror`, `status`, `is_fork`, `fork_id`, `is_template`, `template_id`, `size`, `is_fsck_enabled`, `close_issues_via_commit_in_any_branch`, `topics`, `avatar`, `created_unix`, `updated_unix` FROM `repository` ORDER BY updated_unix DESC LIMIT 15 OFFSET 45
Returns different results for MySQL than other engines. However, the similar query:
SELECT `id`, `owner_id`, `owner_name`, `lower_name`, `name`, `description`, `website`, `original_service_type`, `original_url`, `default_branch`, `num_watches`, `num_stars`, `num_forks`, `num_issues`, `num_closed_issues`, `num_pulls`, `num_closed_pulls`, `num_milestones`, `num_closed_milestones`, `is_private`, `is_empty`, `is_archived`, `is_mirror`, `status`, `is_fork`, `fork_id`, `is_template`, `template_id`, `size`, `is_fsck_enabled`, `close_issues_via_commit_in_any_branch`, `topics`, `avatar`, `created_unix`, `updated_unix` FROM `repository` ORDER BY updated_unix DESC LIMIT 15 OFFSET 30
Returns the same results.
This causes integration tests to fail on MySQL in certain cases but would never show up in a real installation. Since this API call always returns issues based on the optionally provided repo_priority_id or the issueID itself, there is no change to results by changing the repo sorting method used to get ids earlier in the function.
