bdrv_read/write emulation is used as the perfect example why we need something
like AsyncContexts. So maybe they better start using it.

Add the possibility to use AIO and BHs without allowing foreign callbacks to be
run. Basically, you put your own AIOs and BHs in a separate context. For
details see the comments in the source.

Instead of putting more and more stuff into vl.c, let's have the generic
functions that deal with asynchronous callbacks in their own file.

We'll leave some AIO completions unhandled when we can't call the callback.
qemu_aio_process_queue() is used later to run any callbacks that are left and
can be run then.

We need to process the request queue and run callbacks separately from reading
out the queue in a later patch, so split it out.
