Don't ignore native CROSSING_GRAB/UNGRAB events

Browse Source 
These are sent when someone else grabs the pointer, and we don't
want to miss these expose events. For instance, we missed enter
and leave events on alt-tab.

There were some issues with these wrt out-of-sync grab information
in the client, but that should now be handled. So, it should work
or at least be fixable if we find some bug.
