In XWayland, dri3_send_open_reply() is called from a sync callback, so
there is a possibility that the client might be gone when we get to the
callback eventually, which leads to a crash in _XSERVTransSendFd() from
WriteFdToClient() .
Client resources can survive the client itself, in which case we
may end up in our sync callback trying to access client's data after
it's been freed/reclaimed.
Add a ClientStateCallback handler to monitor the client state changes
and clear the sync callback set up by the glamor drm code if any.
