monitor: only run coroutine commands in qemu_aio_context monitor_qmp_dispatcher_co() runs in the iohandler AioContext that is not polled during nested event loops. The coroutine currently reschedules itself in the main loop's qemu_aio_context AioContext, which is polled during nested event loops. One known problem is that QMP device-add calls drain_call_rcu(), which temporarily drops the BQL, leading to all sorts of havoc like other vCPU threads re-entering device emulation code while another vCPU thread is waiting in device emulation code with aio_poll(). Paolo Bonzini suggested running non-coroutine QMP handlers in the iohandler AioContext. This avoids trouble with nested event loops. His original idea was to move coroutine rescheduling to monitor_qmp_dispatch(), but I resorted to moving it to qmp_dispatch() because we don't know if the QMP handler needs to run in coroutine context in monitor_qmp_dispatch(). monitor_qmp_dispatch() would have been nicer since it's associated with the monitor implementation and not as general as qmp_dispatch(), which is also used by qemu-ga. A number of qemu-iotests need updated .out files because the order of QMP events vs QMP responses has changed. Solves Issue #1933.
