Fix 64-bit atomic operations on 32-bit machines (#19531) (#19532)
- Backport #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

Restart zero worker if there is still work to do (#18658) (#18672)
* Restart zero worker if there is still work to do (#18658)

Backport #18658

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.

Only attempt to flush queue if the underlying worker pool is not finished (#18593) (#18620)
* Only attempt to flush queue if the underlying worker pool is not finished (#18593)

Backport #18593

There is a possible race whereby a worker pool could be cancelled but yet the
underlying queue is not empty. This will lead to flush-all cycling because it
cannot empty the pool.

* On shutdown of Persistant Channel Queues close datachan and empty

Partial Backport #18415

Although we attempt to empty the datachan in queues - due to
races we are better off just closing the channel and forcibly emptying
it in shutdown.

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

* move persistable channel shutdown stuff to Shutdown Fn

* Ensure that UPCQ has the correct config

* handle shutdown during the flushing

* reduce risk of race between zeroBoost and addWorkers

* prevent double shutdown

Only use boost workers for leveldb shadow queues (#15696)
* The leveldb shadow queue of a persistable channel queue should always start with 0
workers and just use boost to add additional workers if necessary.

* create a zero boost so that if there are no workers in a pool - boost to start the workers

* actually set timeout appropriately on boosted workers

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.
