Stefan Hajnoczi e8ee5e4c47 coroutine: add qemu_co_queue_restart_all()
It's common to wake up all waiting coroutines.  Introduce the
qemu_co_queue_restart_all() function to do this instead of looping over
qemu_co_queue_next() in every caller.

Kevin Wolf e680cfa7e2 coroutines: Use one global bottom half for CoQueue
Now that AsyncContexts don't exist any more, we can use one global bottom half
for restarting coroutines instead of allocating a new one every time (before
removing AsyncContexts, the problem with having a global BH was that it had to
belong to a single AsyncContexts and wouldn't be executed in a different one -
which leads to deadlocks)
