Fix 64-bit atomic operations on 32-bit machines (#19531)
- Doing 64-bit atomic operations on 32-bit machines is a bit tricky by
golang, as they can only be done under certain set of
conditions(https://pkg.go.dev/sync/atomic#pkg-note-BUG).
- This PR fixes such case whereby the conditions weren't met, it moves
the int64 to the first field of the struct, which will 64-bit operations
happening on this property on 32-bit machines.
- Resolves #19518

Prevent intermittent NPE in queue tests (#19301)
There appears to be an intermittent NPE in queue tests relating to the deferred
shutdown/terminate functions.

This PR more formally asserts that shutdown and termination occurs before starting
and finishing the tests but leaves the defer in place to ensure that if there is an
issue shutdown/termination will occur.

Add Goroutine stack inspector to admin/monitor (#19207)
Continues on from #19202.

Following the addition of pprof labels we can now more easily understand the relationship between a goroutine and the requests that spawn them. 

This PR takes advantage of the labels and adds a few others, then provides a mechanism for the monitoring page to query the pprof goroutine profile.

The binary profile that results from this profile is immediately piped in to the google library for parsing this and then stack traces are formed for the goroutines.

If the goroutine is within a context or has been created from a goroutine within a process context it will acquire the process description labels for that process. 

The goroutines are mapped with there associate pids and any that do not have an associated pid are placed in a group at the bottom as unbound.

In this way we should be able to more easily examine goroutines that have been stuck.

A manager command `gitea manager processes` is also provided that can export the processes (with or without stacktraces) to the command line.

Simplify Boost/Pause logic (#18673)
* Simplify Boost/Pause logic

#18658 has added a check to see if we need to boost because there is still work to do
however the check is slightly complex and not ideal. There's no point boosting if
the queue is paused or can't scale. Therefore merge the two selects into one and add
a check to p.paused.

Restart zero worker if there is still work to do (#18658)
* Restart zero worker if there is still work to do

It is possible for the zero worker to timeout before all the work is finished.
This may mean that work may take a long time to complete because a worker will only
be induced on repushing.

Also ensure that requested count is reset after pulls and push mirror sync requests and add some more trace logging to the queue push.

Make the Mirror Queue a queue (#17326)
Convert the old mirror syncing queue to the more modern queue format.

Fix a bug in the from the repo-archive queue PR - the assumption was made that uniqueness could be enforced with by checking equality in a map in channel unique queues - however this only works for primitive types - which was the initial intention but is an imperfect. This is fixed by marshalling the data and placing the martialled data in the unique map instead.

The documentation is also updated to add information about the deprecated configuration values.

Timeout on flush in testing (#16864)
* Timeout on flush in testing

At the end of each test the queues are flushed. At present there is no limit on the
length of time a flush can take which can lead to long flushes.

However, if the CI task is cancelled we lose the log information as to where the long
flush was taking place.

This PR simply adds a default time limit of 2 minutes - at which point an error will
be produced. This should allow us to more easily find the culprit.

Multiple Queue improvements: LevelDB Wait on empty, shutdown empty shadow level queue, reduce goroutines etc (#15693)
* move shutdownfns, terminatefns and hammerfns out of separate goroutines

Coalesce the shutdownfns etc into a list of functions that get run at shutdown
rather then have them run at goroutines blocked on selects.

This may help reduce the background select/poll load in certain
configurations.

* The LevelDB queues can actually wait on empty instead of polling

Slight refactor to cause leveldb queues to wait on empty instead of polling.

* Shutdown the shadow level queue once it is empty

* Remove bytefifo additional goroutine for readToChan as it can just be run in run

* Remove additional removeWorkers goroutine for workers

* Simplify the AtShutdown and AtTerminate functions and add Channel Flusher

* Add shutdown flusher to CUQ

Prevent timer leaks in Workerpool and others (#11333)
There is a potential memory leak in `Workerpool` due to the intricacies of
`time.Timer` stopping.

Whenever a `time.Timer` is `Stop`ped its channel must be cleared using a
`select` if the result of the `Stop()` is `false`.

Unfortunately in `Workerpool` these were checked the wrong way round.

However, there were a few other places that were not being checked.
