[PATCH] Send events that were missing from RRSelectInput

[Federico Mena Quintero]

The RANDR spec (randrproto.txt) specifies that RRSelectInput will send out
events corresponding to the event mask, if there have been changes to
CRTCs or outputs.  Only screen events were being generated, however.

Fixes http://bugs.freedesktop.org/21760
