mesa: Fix setup of LocalParams array.

i965 passed piglit, but swrast and gallium both segfaulted without this.
i965 happened to work because it never ran _mesa_load_state_parameters()
on the new program before the test called glProgramLocalParameter(), which
was allocating a LocalParams array for the fallback path.

v2: Since v1 threw away old localparams data, leaked old LocalParams
    memory, only fixed fragment programs, and I was dubious of my previous

    LocalParams, and only that one path of program_parse.y will), just
    late-allocate localparams at the other point of dereferencing them.

u_gen_mipmap: Use untampered cubemap texture coords when generating mipmaps.

It's not necessary to scale down cubemap texture coords when generating
mipmaps: we are doing a 2x minification therefore it's guaranteed that
the texture coords will always be at least 1 texel away of the edges.

Scaling down can actually be harmful, as it may cause artefacts when
generating mipmaps with nearest filtering.  Sample points will lie
exactly in the middle each 2x2 texels, so the scaling factor was causing
different texels to be take on each quadrant of the cube face.  This is
apparent with a 1x1 checkerboard pattern in the base mipmap level:
instead of next mipmap level receiving a constant color throughout the
face, it will have different colors for each quadrant of the face.

The behaviour for blits is left untouched for now, but the cubemap

mesa: Dynamically allocate the storage for program local parameters.

The array was 64kb per struct gl_program, plus we statically stored a copy
of one on disk for _mesa_DummyProgram.  Given that most struct gl_programs
we generate are for GLSL shaders that don't have local parameters, this
was a waste.

Since you can store and fetch parameters beyond what the program actually
uses, we do have to do a late allocation if necessary at
GetProgramLocalParameter time.

i965: Rework brw_new_batch to actually start a new batch.

Previously, brw_new_batch was called just after execbuf, but before
intel_batchbuffer_reset.  Essentially, it prepared for the creation of a
new batch, that wasn't yet available, and which it didn't create.  This
was a bit awkward.

This patch makes brw_new_batch call intel_batchbuffer_reset as the very
first operation.  This means that brw_new_batch actually creates a new
batchbuffer, and thus has it available.  It brings the creation of the
new batchbuffer and BRW_NEW_BATCH flagging together into one place.

i915: Actually enable __DRI2rendererQueryExtensionRec

More rebase fail.  This code was written long before i915 and i965 were
split, so most of the code in i9[16]5/intel_screen.c only needed to
exist in one place.  It looks like I fixed n-1 of those places after
rebasing on the split.

I only found this from the defined-but-not-used warning for
intelRendererQueryExtension.  I noticed this while fixing the other,
related warnings.

(Note: During review, we decided to *not* pick this back to 10.0.)
