Replace xf86ValidateModes usage with a set of custom validators and pruning.

This moves us to maintaining MonPtrs per pipe instead of using the EDID
structure "xf86MonPtr", which is closer to what we want to be looking at when
doing validation.  The new validation isn't enough yet -- particularly, we
aren't importing and validating the custom modelines to the pipes when
applicable, but this will be easier than (for example) trying to make flat
panel modes pass xf86ValidateModes through various gross hacks.

Hotplug turn-on/off also happens at SwitchMode time now, instead of at randr
probe time.
