[Qemu-devel] [PATCH v6 24/28] io: let watcher of the channel run in same ctx |

Per-thread gcontext is only used in IOThread (please refer to callers of
g_main_context_push_thread_default), so this patch only affects anything
that will be run in an IOThread. It lets the watcher object be run in
the same context as the caller that added the watcher.
This patch is critical to make sure that migration stream accept()
procedure will also be run in the monitor IOThread rather than the
default main thread, so it can survive even if main thread hangs.
