Catch the error before the response is processed by goth. (#20000)
The code introduced by #18185 gets the error from response after it was processed by goth.
That is incorrect, as goth (and golang.org/x/oauth) doesn't really care about the error, and it sends a token request with an empty authorization code to the server anyway, which always results in a `oauth2: cannot fetch token: 400 Bad Request` error from goth.
It means that unless the "state" parameter is omitted from the error response (which is required to be present, according to [RFC 6749, Section 4.1.2.1](https://datatracker.ietf.org/doc/html/rfc6749#section-4.1.2.1)) or the page is reloaded (makes the session invalid), a 500 Internal Server Error page will be displayed.
This fixes it by handling the error before the request is passed to goth.
Respond with a 401 on git push when password isn't changed yet (#20026)
If the user-agent starts with git and user must change password but
hasn't return a 401 with the message.
It must be a 401, git doesn't seem to show the contents of the error message
when we return a 403
Fixes #19090
There appears to be a strange bug whereby the comment_id index can sometimes be missed
or missing from the action table despite the sync2 that should create it in the earlier
part of this migration. However, looking through the code for Sync2 there is no need
for this pre-code to exist and Sync2 should drop/create the indices as necessary.
I think therefore we should simplify the migration to simply be Sync2.

* make fmt
* dont drop err
* Make sure API responses always refer to username in original case
Copied from what I wrote on #19133 discussion: Handling username case is a very tricky issue and I've already encountered a Mastodon <-> Gitea federation bug due to Gitea considering Ta180m and ta180m to be the same user while Mastodon thinks they are two different users. I think the best way forward is for Gitea to only use the original case version of the username for federation so other AP software don't get confused.
* Move httpsig algs constant slice to modules/setting/federation.go
* Add new federation settings to app.example.ini and config-cheat-sheet
* Return if marshalling error
* Make sure Person IRIs are generated correctly
This commit ensures that if the setting.AppURL is something like "http://127.0.0.1:42567" (like in the integration tests), a trailing slash will be added after that URL.
* If httpsig verification fails, fix Host header and try again
This fixes a very rare bug when Gitea and another AP server (confirmed to happen with Mastodon) are running on the same machine, Gitea fails to verify incoming HTTP signatures. This is because the other AP server creates the sig with the public Gitea domain as the Host. However, when Gitea receives the request, the Host header is instead localhost, so the signature verification fails. Manually changing the host header to the correct value and trying the veification again fixes the bug.
* Revert "If httpsig verification fails, fix Host header and try again"
This reverts commit f53e46c721.
The bug was actually caused by nginx messing up the Host header when reverse-proxying since I didn't have the line `proxy_set_header Host $host;` in my nginx config for Gitea.
* Go back to using ap.IRI to generate inbox and outbox IRIs
* use const for key values
* Update routers/web/webfinger.go
* Use ctx.JSON in Person response to make code cleaner
* Revert "Use ctx.JSON in Person response to make code cleaner"
This doesn't work because the ctx.JSON() function already sends the response out and it's too late to edit the headers.

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`

Allow git push to work when networked file systems with mixed
ownership are used with Gitea docker images >= 1.16.6 or Gitea
binaries running alongside git versions published after 04/2022.
There are circumstances independent of Gitea (networked file systems
with various permission systems) by which the git repositories managed
by Gitea may have mixed owners. It is not a behavior that Gitea have
control over nor is it a problem as long as the permissions for Gitea to
operate are correct. Gitea instances have been operating under these
conditions for a number of years.
It is detected as a potential security risk ( see
GHSA-vw2c-22j4-2fh2
) by the most recent git versions. However, Gitea always runs git
commands with a current directory matching the repository on
which it operates. That makes Gitea immune from this security problem
and it is safe to ignore the mixed owner permission check.
This gitconfig modification is done on a file dedicated to the user
exclusively used by Gitea.

- Fomantic tries to prevent overflowing on the `y/x`-as by default on
stackable menu's on mobile screens. We already solve this issue by
forcing overflow on x as and hide it on y as(due to some issues with
other menu's), since https://github.com/go-gitea/gitea/pull/19486.
- However this edge case does require a y-overflow to show the dropdown,
because you cannot easily adjust this with CSS, once you're fiddling
with overflow's (https://stackoverflow.com/a/6433475). However
interesting behavior is noted
https://css-tricks.com/popping-hidden-overflow/ when you remove the
position: relative, it will suddenly work again. Well because this is
the only solution without redesigning dropdowns, I think we can live
with the side-effect of the dropdown items being full-width instead
"relative" width to their parent.
