Prevent intermittent NPE in queue tests ()
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.

Attempt to prevent the deadlock in the QueueDiskChannel Test again ()
* Attempt to prevent the deadlock in the QueueDiskChannel Test again

This time we're going to adjust the pause tests to only test the right
flag.

* Only switch off pushback once we know that we are not pushing anything else
* Ensure full redirection occurs
* More nicely handle a closed datachan
* And handle similar problems in queue_channel_test

Prevent deadlocks in persistable channel pause test ()
* Prevent deadlocks in persistable channel pause test

Because of reuse of the old paused/resumed channels in this test there
was a potential for deadlock. This PR ensures that the channels are always
reobtained.

It further adds some control code to detect hangs in future - and it
ensures that the pausing warning is not shown on shutdown.

refactor: move from io/ioutil to io and os package ()
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

This PR simply adds locking to prevent the race.

Multiple Queue improvements: LevelDB Wait on empty, shutdown empty shadow level queue, reduce goroutines etc ()
* 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
