qcow2: flush in qcow2_update_snapshot_refcount()

Users of qcow2_update_snapshot_refcount() do not flush consistently.
qcow2_snapshot_create() flushes but qcow2_snapshot_goto() and
qcow2_snapshot_delete() do not.

Solve this by moving the bdrv_flush() into...

qcow2: drop flush in update_cluster_refcount()

The update_cluster_refcount() function increments/decrements a cluster's
refcount and then returns the new refcount value.

There is no need to flush since both update_cluster_refcount() callers
already take care of this:...

qcow2: drop unnecessary flush in qcow2_update_snapshot_refcount()

We already flush when the function completes. There is no need to flush
after every compressed cluster.

qcow2: make is_allocated return true for zero clusters

Otherwise, live migration of the top layer will miss zero clusters and
let the backing file show through. This also matches what is done in qed.

QCOW2_CLUSTER_ZERO clusters are invalid in v2 image files. Check this...

sheepdog: use non-blocking fd in coroutine context

Using a blocking socket in the coroutine context reduces the chance of
switching to other work. This patch makes the sheepdog driver use a
non-blocking fd always.

sheepdog: set io_flush handler in do_co_req

If an io_flush handler is not set, qemu_aio_wait doesn't invoke
callbacks.

main-loop: add qemu_get_aio_context()

It is very useful to get the main loop AioContext, which is a static
variable in main-loop.c.

I'm not sure whether qemu_get_aio_context() will be necessary in the
future once devices focus on using their own AioContext instead of the...

threadpool: move globals into struct ThreadPool

Move global variables into a struct so multiple thread pools can be
supported in the future.

This patch does not change thread-pool.h interfaces. There is still a
global thread pool and it is not yet possible to create/destroy...

threadpool: add thread_pool_new() and thread_pool_free()

ThreadPool is tied to an AioContext through its event notifier, which
dictates in which AioContext the work item's callback function will be
invoked.

In order to support multiple AioContexts we need to support multiple...

aio: add a ThreadPool instance to AioContext

This patch adds a ThreadPool to AioContext. It's possible that some
AioContext instances will never use the ThreadPool, so defer creation
until aio_get_thread_pool().

The reason why AioContext should have the ThreadPool is because the...
