aio: return "AIO in progress" state from qemu_aio_wait

The definition of when qemu_aio_flush should loop is much simpler
than it looks. It just has to call qemu_aio_wait until it makes
no progress and all flush callbacks return false. qemu_aio_wait
is the logical place to tell the caller about this....

Add qemu_aio_process_queue()

qemu_aio_process_queue() is used later to run any callbacks that are left and
can be run then.

fix qemu_aio_flush

qemu_aio_wait by invoking the bh or one of the aio completion
callbacks, could end up submitting new pending aio, breaking the
invariant that qemu_aio_flush returns only when no pending aio is
outstanding (possibly a problem for migration as such)....

Refactor AIO to allow multiple AIO implementations

This patch refactors the AIO layer to allow multiple AIO implementations. It's
only possible because of the recent signalfd() patch.

Right now, the AIO infrastructure is pretty specific to the block raw backend....
