fbd9cc6169 st/mesa: don't return an error from update_single_texture 
It can just return a NULL sampler view, which is better than not doing
anything at all.

4d6fab245e cso: don't track the number of sampler states bound 
This removes 2 loops from hot codepaths and adds 1 loop to a rare codepath
(restore_sampler_states), and makes sanitize_hash() slightly worse.

Sampler states, when bound, are not unbound for draw calls that don't need
them. That's OK, because bound sampler states don't add any overhead.

This results in lower CPU overhead in most cases.

585c5cf8a5 mesa: don't update draw buffer bounds in _mesa_update_state 
st/mesa doesn't need the draw bounds for draw calls. I've added the call
where it's necessary in core Mesa and drivers, but I suspect that most
drivers can just move the call to the right places.

The core Mesa places aren't hot paths, so the call overhead doesn't matter
there.

For now, only st/mesa is made such that this function is invoked very
rarely.

This bypasses _mesa_update_state_locked.

Before:

   DrawArrays   ( 1 VBOs, 4 UBOs,  8 Tex) w/ stencil enable change:    4.56 million

After:
   DrawElements ( 1 VBOs, 4 UBOs,  8 Tex) w/ stencil enable change:    4.93 million
   DrawArrays   ( 1 VBOs, 4 UBOs,  8 Tex) w/ stencil enable change:    5.84 million

It's quite a difference in the draw call rate when ctx->NewState stays
equal to 0 the whole time.
