Introduce RequestContext: is a short-lived context that is used to store
request-specific data.
RequestContext could be used to clean form tmp files, close context git
repo, and do some tracing in the future.
Then a lot of legacy code could be removed or improved. For example:
most `ctx.Repo.GitRepo.Close()` could be removed because the git repo
could be closed when the request is done.
After many refactoring PRs for the "locale" and "template context
function", now the ".locale" is not needed for web templates any more.
This PR does a clean up for:
1. Remove `ctx.Data["locale"]` for web context.
2. Use `ctx.Locale` in `500.tmpl`, for consistency.
3. Add a test check for `500 page` locale usage.
4. Remove the `Str2html` and `DotEscape` from mail template context
data, they are copy&paste errors introduced by #19169 and #16200 . These
functions are template functions (provided by the common renderer), but
not template data variables.
5. Make email `SendAsync` function mockable (I was planning to add more
tests but it would make this PR much too complex, so the tests could be
done in another PR)
This PR removed `unittest.MainTest` the second parameter
`TestOptions.GiteaRoot`. Now it detects the root directory by current
working directory.

The admin config page has been broken for many many times, a little
refactoring would make this page panic.
So, add a test for it, and add another test to cover the 500 error page.
