fgprof is a sampling Go profiler that allows you to analyze On-CPU as
well as Off-CPU (e.g. I/O) time together.
Go's builtin sampling CPU profiler can only show On-CPU time, but it's
better than fgprof at that. Go also includes tracing profilers that can
analyze I/O, but they can't be combined with the CPU profiler.
fgprof is designed for analyzing applications with mixed I/O and CPU
workloads. This kind of profiling is also known as wall-clock profiling.
Whilst fgprof can cause significant STW latencies in applications with a
lot of goroutines (> 1-10k), these latencies only occur if the profile
is requested - it doesn't cause a delay by simply being available.
The fgprof profile is mounted on
`http://localhost:6060/debug/fgprof?seconds=3`

Continues on from #19202.
Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them.
This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.
The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.
If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process.
The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.
In this way we should be able to more easily examine goroutines that have been stuck.
A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

Make router logger more friendly, show the related function name/file/line.
[BREAKING]
This PR substantially changes the logging format of the router logger. If you use this logging for monitoring e.g. fail2ban you will need to update this to match the new format.
* Improve install code to avoid low-level mistakes.
If a user tries to do a re-install in a Gitea database, they gets a warning and double check.
When Gitea runs, it never create empty app.ini automatically.
Also some small (related) refactoring:
* Refactor db.InitEngine related logic make it more clean (especially for the install code)
* Move some i18n strings out from setting.go to make the setting.go can be easily maintained.
* Show errors in CLI code if an incorrect app.ini is used.
* APP_DATA_PATH is created when installing, and checked when starting (no empty directory is created any more).
* Simplify Gothic to use our session store instead of creating a different store
We have been using xormstore to provide a separate session store for our OAuth2 logins
however, this relies on using gorilla context and some doubling of our session storing.
We can however, simplify and simply use our own chi-based session store. Thus removing
a cookie and some of the weirdness with missing contexts.

Although panics within the rendering pipeline are caught and dealt with,
panics that occur before that starts are unprotected and will kill Gitea
without being sent to the logs.
This PR adds a basic recovery handler to catch panics that occur after
the logger is initialised and ensure that they're sent to the logger.

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.

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.

* Fix --port setting
Unfortunately there was an error in #13195 which set the --port
option before the settings were read. This PR fixes this by
moving applying this option to after the the settings are read
However, on looking further into this code I believe that the setPort
code was slightly odd.
Firstly, it may make sense to run the install page on a different
temporary port to the full system and this should be possible with
a --install-port option.
Secondy, if the --port option is provided we should apply it to both
otherwise there will be unusual behaviour on graceful restart
Thirdly, the documentation for --port says that the setting is
temporary - it should therefore not save its result to the configuration
(This however, does mean that authorized_keys and internal links may
not be correct. - I think we need to discuss this option further.)

#12391 offered to change the default PID file from /var/run/gitea.pid however in discussion it was decided that this could break users of older systems. An alternative was offered that we could make the PID file compile/link time settable.
This PR does this, and changes the name of the setting from CustomPID to simply PIDFile. It also updates the from-source docs to show how to change the compiler settings to do this.

Closes#5280
* Fix a typo
* Add an option to allow redirect of http port 80 to https.
This is an "opt in" option (default is to not redirect). It will only redirect
if protocol is https and the new REDIRECT_PORT_80 option is set to true.
The Port to redirect in previous commit was hardcoded to 80, now it can be
specified in the app.ini, defaulting to 80. The boolean option to turn
redirection on has been changed to REDIRECT_OTHER_PORT to be logically
consistent with the new port option.
