Remove two unmaintained vendor packages `i18n` and `paginater`. Changes:
* Rewrite `i18n` package with a more clear fallback mechanism. Fix an unstable `Tr` behavior, add more tests.
* Refactor the legacy `Paginater` to `Paginator`, test cases are kept unchanged.
Trivial enhancement (no breaking for end users):
* Use the first locale in LANGS setting option as the default, add a log to prevent from surprising users.
This PR continues the work in #17125 by progressively ensuring that git
commands run within the request context.
This now means that the if there is a git repo already open in the context it will be used instead of reopening it.

* Prevent double sanitize.
* Use SanitizeReaderToWriter.
At the moment `actualRender` uses `SanitizeReader` to sanitize the output. But `SanitizeReader` gets called in `markup.render` too so the output gets sanitized twice.
I moved the `SanitizeReader` call into `RenderRaw` because this method does not use `markup.render`. I would like to remove the `RenderRaw`/`RenderRawString` methods too because they are only called from tests, the fuzzer and the `/markup/raw` api endpoint. This endpoint is not in use so I think we could remove them. If we really in the future need a method to render markdown without PostProcessing we could achieve this with a more flexible `renderer.NeedPostProcess` method.

GH has different HardBreaks behaviour for markdown comments and documents.
Comments have hard breaks and documents have soft breaks - therefore Gitea's rendering will always be different from GH's if we only provide one setting.
Here we split the setting in to two - one for documents and one for comments and other things.

* Don't manually replace whitespace during render
For historical reasons Gitea manually alters the urlPrefix and replaces
a whitespace with a +. This Works for URLs, but we're also passing
urlPrefix to git calls and adding the + is breaking the tree path.
Goldmark will automatically convert a white space to the proper %20, so
we should leave the string as is which lets us pass it to git unmodified
and then let Goldmark fix it.
Also fixed separate bug in URLJoin I noticed while testing where it will
silently discard sections of a path that have # in them (possibly
others). We should just escape it first.

* Move to goldmark
Markdown rendering moved from blackfriday to the goldmark.
Multiple subtle changes required to the goldmark extensions to keep
current rendering and defaults.
Can go further with goldmark linkify and have this work within markdown
rendering making the link processor unnecessary.
Need to think about how to go about allowing extensions - at present it
seems that these would be hard to do without recompilation.
