The current default memory cache implementation is unbounded in size and number of
objects cached. This is hardly ideal.
This PR proposes creating a TwoQueue LRU cache as the underlying cache for Gitea.
The cache is limited by the number of objects stored in the cache (rather than size)
for simplicity. The default number of objects is 50000 - which is perhaps too small
as most of our objects cached are going to be much less than 1kB.
It may be worth considering using a different LRU implementation that actively limits
sizes or avoids GC - however, this is just a beginning implementation.

* Update models/login_source.go
One of the repeatedly reported issues has been that gitea produces too much console
logging during set up even if the console logger is turned off.
Fundamentally this is due to some otherwise very helpful logging that has to occur
before logging is set up. This has come to a head with the merging of #16243 where
otherwise potentially helpful Trace logging in the git module now appears on the
console.
This PR proposes three things:
1. Change the initial default logger to Info not Trace.
2. Change the logging for the AppPath things to Info in recompense.
3. Add two new command line options to gitea web: --quiet and --verbose
`gitea web -q` or `gitea web --quiet` will only log Fatal level initially.
`gitea web -verbose` will log at Trace.

what seems reasonable is to set some minimum rate we expect for writing.
This PR suggests the following algorithm:
* Every write has a minimum timeout of 5s (adjustable at compile time.)
* If there has been a previous write - then consider its previous
deadline, add half of the minimum timeout + 2s per kb about to written.

The Tor browser does not use the system-ui font and no other fonts in the stack match
its default fonts. In fact it is possible that it will in future only
match generic fonts. This means that all rendering will first try the
emoji fonts before falling back to the sans-serif font for glyphs.
In this case has the emoji fall back fonts for Tor contains empty glyphs
for numbers - in order to protect privacy - and leads to numbers being
rendered as empty glyphs. This is clearly not ideal and whilst we could
use the Arimo font - as I state above I suspect that Tor will eventually
ban detecting this and we should instead move the sans-serif font higher
in the stack so that it matches before the emoji fonts.

* Prevent double-login for Git HTTP and LFS and simplify login
There are a number of inconsistencies with our current methods for
logging in for git and lfs. The first is that there is a double login
process. This is particularly evident in 1.13 where there are no less
than 4 hash checks for basic authentication due to the previous
IsPasswordSet behaviour.
This duplicated code had individual inconsistencies that were not
helpful and caused confusion.
This PR does the following:
* Remove the specific login code from the git and lfs handlers except
for the lfs special bearer token
* Simplify the meaning of DisableBasicAuthentication to allow Token and
Oauth2 sign-in.
* The removal of the specific code from git and lfs means that these
both now have the same login semantics and can - if not
DisableBasicAuthentication - login from external services. Further it
allows Oauth2 token authentication as per our standard mechanisms.
* The change in the recovery handler prevents the service from
re-attempting to login - primarily because this could easily cause a
further panic and it is wasteful.
