xwayland/xwm: implement somewhat asynchronous request flushing

Browse source 
Instead of calling xcb_flush() directly, wait until the FD is
writable.

Ideally we'd have a non-blocking variant instead of xcb_flush(),
but libxcb doesn't have this. Also libxcb blocks when its internal
buffer is full, but not much we can do here.
