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`

It appears possible that stopwatches can become orphaned or have been orphaned in
the past.
This PR adds Orphan checks for Stopwatches.

* Empty log queue on flush and close
It is possible for log events to remain in the buffer off the multichannelledlog
and thus not be logged despite close or flush.
This PR simply adds a function to empty the queue before closing or flushing.
(Except when the logger is paused.)

If there are dangling stopwatches with missing issues there will be repeated
logging of Unable to APIFormat stopwatches. These are unhelpful and instead
we should only log if the error is not an issue not exist error.
And we should also prevent an error on missing issue in GetActiveStopwatch too

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.

For some reason I didn't realize that /templates/swagger/v1_json.tmpl was machine-generated by make generate-swagger... I've been editing it by hand for three months! 🤦
