glsl: fix compiler warnings in link_uniforms.cpp

With a non-debug build, gcc has two complaints:
1. 'found' var not used.  Silence with '(void) found;'
2. 'id' not initialized.  It's assigned by the UniformHash->get()
   call, actually.  But init it to zero to silence gcc.

st/mesa: Add R8G8B8A8_SRGB case to st_pipe_format_to_mesa_format.

With the recent SRGB changes all my automated OpenGL llvmpipe tests
(piglit, conform, glretrace) start asserting with the backtrace below.

I'm hoping this change will fix it.  I'm not entirely sure, as this
doesn't happen in my development machine (the bug probably depends on
the exact X visual).

Anyway, it seems the sensible thing to do here.

i965: Fix render-to-texture in non-FinishRenderTexture cases.

We've had several problems now with FinishRenderTexture not getting called
enough, and we're ready to just give up on it ever doing what we need.  In
particular, an upcoming Steam title had rendering bugs that could be fixed
by always_flush_cache=true.

Instead of hoping Mesa core can figure out when we need to flush our
caches, just track what BOs we've rendered to in a set, and when we render
from a BO in that set, emit a flush and clear the set.

There's some overhead to keeping this set, but most of that is just
hashing the pointer -- it turns out our set never even gets very large,
because cache flushes are so common (even on cairo-gl).

No statistically significant performance difference in cairo-gl (n=100),
despite spending ~.5% CPU in these set operations.

v1: (Original patch by Eric Anholt.)
v2: (Changes by Ken Graunke.)
  - Rebase forward from May 7th 2013 -> March 4th 2014.
  - Drop the FinishRenderTexture hook entirely; after rebasing the
    patch, the hook was just an empty function.
  - Move the brw_render_cache_set_clear() call from
    intel_batchbuffer_emit_flush() to brw_emit_pipe_control_flush().
    In theory, this could catch more cases where we've flushed.
  - Consider stencil as a possible texturing source.
v3: (changes by anholt):
  - Move set_clear() back to emit_mi_flush() -- it means we can drop
    more forced flushes from the code.  In the previous location, it
    wouldn't have been called when we wanted pre-gen6.
  - Move the set clear from batch init to reset -- it should be empty at
    the start of every batch, since the kernel handled any inter-batch
    flush for us.
v4: Drop the debug code in set.c that I accidentally committed.
