export {Start,End}GraphicsExposures from x11drv

[Dimitrie O. Paun]

This is a small patch to prepare things for future work
(to be shipped in a few minutes:))

Fundamentally, the main purpose of a USER driver is to deal 
with windowing, and as such, it needs to be able to compute 
invalidated areas. It thus makes sense to for it to export
functions that let you query this information.

The start/end interface used by x11drv makes sense, and it
looks sane enough to be exported.

ChangeLog
  Export {Start,End}GraphicsExposures from x11drv.
