"Handle" events during startup (FS#877)

Browse source 
awesome.c contains this comment:

    There can be no events yet, so if his function returns something, it must be
    an error.

Sadly, this wasn't true. It seems like something managed to generate
MappingNotify events (no idea how).

Fix this by discarding all pending events after our GrabServer, but before we
ask for SubstructureRedirect on the root window.
