[PATCH] dri2: Don't block GLX clients on VT switch

[Adam Jackson]

This was necessary in DRI1 for a variety of reasons (SAREA ownership,
VRAM layout, etc).  None of that is relevant to DRI2.  Tested with Gnome
3 on an Ironlake GPU.

As a pleasant side effect, we no longer need the ScrnInfoRec type, which
means DRI2 is (at least very nearly) DDX-independent.
