Sending this out now that NBD's incorrect uses have been fixed.
There is no equivalent of qemu_co_queue_enter_next that restarts all
coroutines but that is incorrect because qemu_co_queue_restart_all should
really be a coroutine_fn. The NBD uses have been fixed by removing the
calls to qemu_co_queue_restart_all; graphic_hw_update_done works just
because it uses the BQL; but the new rwlock for the BlockDriverState
graph will need it.
The series introduces the new function, removes some duplicated code
around it, and marks qemu_co_queue_next and qemu_co_queue_restart_all
as coroutine_fn.
