fix #25924

Backport #25648

Replace #25580

Fix #19453

The problem was: when users set "GITEA__XXX__YYY" , the "install page"
doesn't respect it.

So, to make the result consistent and avoid surprising end users, now
the "install page" also writes the environment variables to the config
file.

And, to make things clear, there are enough messages on the UI to tell
users what will happen.

There are some necessary/related changes to `environment-to-ini.go`:

* The "--clear" flag is removed and it was incorrectly written there.
The "clear" operation should be done if INSTALL_LOCK=true
* The "--prefix" flag is removed because it's never used, never
documented and it only causes inconsistent behavior.

The only conflict during backport is "ui divider" in
templates/install.tmpl

Backport #25480 by @wxiaoguang

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"

Backport #25330

# 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.

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

Major changes:

1. Move a lot of code from `environment-to-ini.go` to `config_env.go` to
make them testable.
2. Add `__FILE` support
3. Update documents
4. Add tests

This PR adds support for the systemd notify protocol. Several status

Hello sir,
This pull request solves issue #23949
I have updated the upgrade script such that it will check if the Gitea
service is running, if it's not running then it will exit the process
and if it's running then the process will move further ahead.
Thank You.

Enable [forbidigo](https://github.com/ashanbrown/forbidigo) linter which
forbids print statements. Will check how to integrate this with the
smallest impact possible, so a few `nolint` comments will likely be
required. Plan is to just go through the issues and either:

- Remove the print if it is nonsensical
- Add a `//nolint` directive if it makes sense

I don't plan on investigating the individual issues any further.

It is required to update all import path, in additional to `go.mod`

* Clean the "tools" directory. The "tools" directory contains only two
files, move them.
* The "external_renderer.go" works like "cat" command to echo Stdin to
Stdout , to help testing.
* The `// gobuild: external_renderer` is incorrect, there should be no
space: `//gobuild: external_renderer`
* The `fmt.Print(os.Args[1])` is not a well-defined behavior, and it's
never used.
* The "watch.sh" is for "make watch", it's somewhat related to "build"
* After this PR, there is no "tools" directory, the project root
directory looks slightly simpler than before.
* Remove the legacy "contrib/autoboot.sh", there is no
"gogs_supervisord.sh"
* Remove the legacy "contrib/mysql.sql", it's never mentioned anywhere.
* Remove the legacy "contrib/pr/checkout.go", it has been broken for
long time, and it introduces unnecessary dependencies of the main code
base.

Some bugs caused by less unit tests in fundamental packages. This PR
refactor `setting` package so that create a unit test will be easier
than before.

- All `LoadFromXXX` files has been splited as two functions, one is
`InitProviderFromXXX` and `LoadCommonSettings`. The first functions will
only include the code to create or new a ini file. The second function
will load common settings.
- It also renames all functions in setting from `newXXXService` to
`loadXXXSetting` or `loadXXXFrom` to make the function name less
confusing.
- Move `XORMLog` to `SQLLog` because it's a better name for that.

Maybe we should finally move these `loadXXXSetting` into the `XXXInit`
function? Any idea?

This PR provides a contributed backport command to help create backports
for Gitea.

It represents a significant improvement on my previously described
shell-script.

It can be installed using `go install contrib/backport/backport.go`.

This PR introduces a few minor changes to the gitea-monitoring-mixin,
specifically linting issues raised by
[Mixtool](https://github.com/monitoring-mixins/mixtool):
- Query selectors using `job` and `instance` have been update to allow
multi-select
- Added missing attributes to `job` and `instance` template

As this change is very minor I haven't created an issue, but please let
me know if you'd like me to do so. According to the guidelines, it
seemed to only be for larger designs :)

Change all license headers to comply with REUSE specification.

`LimitMEMLOCK=infinity` is already the default, so removed that

Default soft limit for LimitNOFILE is 1024
Default hard limit for LimitNOFILE is 524288

`LimitNOFILE=65535` increases the soft limit, but decreases the hard

The recovery, API, Web and package frameworks all create their own HTML
Renderers. This increases the memory requirements of Gitea
unnecessarily with duplicate templates being kept in memory.

Further the reloading framework in dev mode for these involves locking
and recompiling all of the templates on each load. This will potentially
hide concurrency issues and it is inefficient.

This PR stores the templates renderer in the context and stores this
context in the NormalRoutes, it then creates a fsnotify.Watcher
framework to watch files.

The watching framework is then extended to the mailer templates which
were previously not being reloaded in dev.

Then the locales are simplified to a similar structure.

Adds an upgrade script that automates upgrading installations on Linux from binary releases, so people don't need to reinvent the wheel. Hopefully this leads to less questions about how to upgrade, and consequently less Gitea instances running unmaintained versions in the wild.

This PR adds gitea-mixin, configurable Grafana dashboards (and potentially prometheus alerts+recording rules) based on Gitea [metrics](https://docs.gitea.io/en-us/config-cheat-sheet/#metrics-metrics).

The overview dashboard is described using jsonnet and grafonnet library: https://grafana.github.io/grafonnet-lib/

Mixins help to define dashboard and alerts as code so they can be collaboratively improved by the users.

![image](https://user-images.githubusercontent.com/14870891/142862822-fe57b384-c74a-4103-8548-033e92f90751.png)

__
## Generate config files

You can manually generate dashboards, but first you should install some tools:

```bash
go get github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb
go get github.com/google/go-jsonnet/cmd/jsonnet
# or in brew: brew install go-jsonnet
```

For linting and formatting, you would also need `mixtool` and `jsonnetfmt` installed. If you
have a working Go development environment, it's easiest to run the following:

```bash
go get github.com/monitoring-mixins/mixtool/cmd/mixtool
go get github.com/google/go-jsonnet/cmd/jsonnetfmt
```

The files in `dashboards_out` need to be imported
into your Grafana server.  The exact details will be depending on your environment.

Edit `config.libsonnet` (for example, list of Gitea metrics to be shown under stats can be adjusted). if required and then build JSON dashboard files for Grafana:

```bash
make
```

Too many docker users are caught out by the default location for the
app.ini file being environment dependent so that when they docker exec
into the container the gitea commands do not work properly and require
additional -c arguments to correctly pick up the configuration.

This PR simply shadows the gitea binary using variants of the FHS
compatible script to make the command gitea have the default locations
by default.

* 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).

* Remove unnecessary variable assignments

* enable ineffassign

* 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.
