aio / timers: Add QEMUTimerListGroup to AioContext

Add a QEMUTimerListGroup each AioContext (meaning a QEMUTimerList
associated with each clock is added) and delete it when the
AioContext is freed.

tests: adjust test-thread-pool to new aio_poll() semantics

aio_poll(ctx, true) will soon block when fd handlers have been set.
Previously aio_poll() would return early if all .io_flush() returned
false. This means we need to check the equivalent of the .io_flush()...

add a header file for atomic operations

We're already using them in several places, but __sync builtins are just

threadpool: drop global thread pool

Now that each AioContext has a ThreadPool and the main loop AioContext
can be fetched with bdrv_get_aio_context(), we can eliminate the concept
of a global thread pool from thread-pool.c.

The submit functions must take a ThreadPool* argument....

tests: avoid qemu_aio_flush() in test-thread-pool.c

We need to eliminate calls to qemu_aio_flush() since the function is
being removed. Most callers will use bdrv_drain_all() instead but
test-thread-pool.c is lower level.

Since the test uses the global AioContext we can loop on qemu_aio_wait()...

tests: make threadpool cancellation test looser

The cancellation test is failing on the buildbots. While the failure
merits a little more investigation to understand what is going on,
the logs show that the failure is not impacting the coverage
provided by the test. Hence, loosen a bit the assertions in a...
