mesa: work-around glXCopyContext() bug in _mesa_copy_texture_state()
See bug 24217.

softpipe: initialize the clear_flags bitvector in sp_create_tile_cache()
This silences tons of valgrind warnings in programs that don't call
glClear(), such as progs/demos/gamma.

softpipe: Grab a ref when the fb is set.
Nasty bug when the surface is freed and another is allocated right on
top of it. The next time we set the fb state SP thinks it's the same
surface and doesn't flush, and when the flush eventually happens the
surface belongs to a completely different texture.
