- Databases are one of the most important parts of Forgejo, every
interaction with Forgejo uses the database in one way or another.
Therefore, it is important to maintain the database and recognize when
Forgejo is not doing well with the database. Forgejo already has the
option to log *every* SQL query along with its execution time, but
monitoring becomes impractical for larger instances and takes up
unnecessary storage in the logs.
- Add a QoL enhancement that allows instance administrators to specify a
threshold value beyond which query execution time is logged as a warning
in the xorm logger. The default value is a conservative five seconds to
avoid this becoming a source of spam in the logs.
- The use case for this patch is that with an instance the size of Codeberg, monitoring SQL logs is not very fruitful and most of them are uninteresting. Recently, in the context of persistent deadlock issues (https://codeberg.org/forgejo/forgejo/issues/220), I have noticed that certain queries hold locks on tables like comment and issue for several seconds. This patch helps to identify which queries these are and when they happen.
- Added unit test.

Mainly for MySQL/MSSQL.
It is important for Gitea to use case-sensitive database charset
collation. If the database is using a case-insensitive collation, Gitea
will show startup error/warning messages, and show the errors/warnings
on the admin panel's Self-Check page.
Make `gitea doctor convert` work for MySQL to convert the collations of
database & tables & columns.
* Fix #28131
## ⚠️ BREAKING ⚠️
It is not quite breaking, but it's highly recommended to convert the
database&table&column to a consistent and case-sensitive collation.
The xorm `Sync2` has already been deprecated in favor of `Sync`,
so let's do the same inside the Gitea codebase.
Command used to replace everything:
```sh
for i in $(ag Sync2 --files-with-matches); do vim $i -c ':%sno/Sync2/Sync/g' -c ':wq'; done
```
The recent change on xorm for `Sync` is it will not warn when database
have columns which is not listed on struct. So we just need this warn
logs when `Sync` the whole database but not in the migrations Sync.
This PR will remove almost unnecessary warning logs on migrations.
Now below logs in CI will disappear.

Replace #23350.
Refactor `setting.Database.UseMySQL` to
`setting.Database.Type.IsMySQL()`.
To avoid mismatching between `Type` and `UseXXX`.
This refactor can fix the bug mentioned in #23350, so it should be
backported.
Change all license headers to comply with REUSE specification.

A lot of our code is repeatedly testing if individual errors are
specific types of Not Exist errors. This is repetitative and unnecesary.
`Unwrap() error` provides a common way of labelling an error as a
NotExist error and we can/should use this.
This PR has chosen to use the common `io/fs` errors e.g.
`fs.ErrNotExist` for our errors. This is in some ways not completely
correct as these are not filesystem errors but it seems like a
reasonable thing to do and would allow us to simplify a lot of our code
to `errors.Is(err, fs.ErrNotExist)` instead of
`package.IsErr...NotExist(err)`
I am open to suggestions to use a different base error - perhaps
`models/db.ErrNotExist` if that would be felt to be better.

* 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).
* Run Migrate in Install rather than just SyncTables
The underlying problem in #17328 appears to be that users are re-running the install
page during upgrades. The function that tests and creates the db did not intend for
this and thus instead the migration scripts being run - a simple sync tables occurs.
This then causes a weird partially migrated DB which causes, in this release cycle,
the duplicate column in task table error. It is likely the cause of some weird
partial migration errors in other cycles too.
This PR simply ensures that the migration scripts are also run at this point too.

* DBContext is just a Context
This PR removes some of the specialness from the DBContext and makes it context
