Hi Eric and all,

this batch prevents setting modes one shouldn't set, adds precise vblank timestamping for interlaced video modes, and one fix for vblank en/disable during crtc en/disable.

All successfully tested, also with timing measurement equipment, on the RPi 2B.

This all seems pretty reasonable to me. My question for modesetting gurus would be: Is mode_fixup the place to be filtering out unsupportable modes from the user (or their displays)?
