Subject: Remove _mesa_ResizeBuffersMESA() call from _mesa_set_viewport(). Now,
 the driver's Viewport routine should call _mesa_ResizeBuffersMESA() if
 necessary. Cleaned up code related to GLframebuffer width/height
 initialization. Set initial viewport/scissor params in _mesa_make_current2(),
 instead of in the drivers' MakeCurrent functions.
