ir_to_mesa: do not check the number of uniforms against hw limits
The r300 compiler can eliminate unused uniforms and remap uniform locations
if their number surpasses hardware limits, so the limit is actually
NumParameters + NumUnusedParameters. This is important for some apps
under Wine to run.
Wine sometimes declares a uniform array of 256 vec4's and some Wine-specific
constants on top of that, so in total there is more uniforms than r300 can
handle. This was the main motivation for implementing the elimination
of unused constants.
We should allow drivers to implement fail & recovery paths where it makes
sense, so giving up too early especially when comes to uniforms is not
so good idea, though I agree there should be some hard limit for all drivers.
This patch fixes:
- glsl-fs-uniform-array-5
- glsl-vs-large-uniform-array
on drivers which can eliminate unused uniforms.

Tested by temporarily using util_clear even when not using the blitter.

i915g: make set_framebuffer_state more robust
u_blitter is lazy and doesn't fully clear it's stack-allocated fb.

i915g: implement hw clear
Benefits:
- spares us a relocation.
- needed for zone rendering (if that ever happens).
- just awesome.
v2: Rename the debug option. Completely disabling the blitter is
required for Y tiling to work, so this option will cover other
code paths in the future.
v3: Implement suggestions by Jakob Bornecrantz.

i915g: streamline derived state updates of the driver pipeline
Flushing the batch/hw backend doesn't invalidate the derived state.
So kill the unnecessary function calls and add an assert in
emit_hardware_state for paranoia.

gallium/util: new polygon stipple utility helper
The polygon stipple fallback does not have to be implemented in the
draw module (it doesn't need window coords, etc). Drivers can use
this utility and avoid sw vertex fallbacks if pstipple is enabled.
Note: this is WIP and not used by any driver yet.
