This adds tokens for texture offsets, to store 4 * swizzled vec 3
for use in TXF and other opcodes.
It also contains TGSI exec changes for softpipe to use this code,
along with GLSL->TGSI support for TXF.
v2: add some more comments, add back padding I removed.

This fixes the swrast failures for piglit's fbo-generatemipmap-formats
test (for uncompressed formats). At some point down the road this code
will go away so I haven't checked all the other store_texel() functions.
Simple demos such as test-opengl-gl_basic work. SurfaceFlinger does not
work yet due to missing GL_OES_draw_texture support (and maybe more).

In preparation for porting i915 to Android, factor its source lists into
a shared makefile. This prevents duplication of source lists, and hence
prevents the Android build from breaking as often.

We don't want to set the pixmap bit in the EGL config if the DRI
config we're adding is a double buffered config. However, don't clear
any other bits the platform might pass in in the surface_type
argument.
Using multiply and reciprocal for integer division involves potentially
lossy floating point conversions. This is okay for older GPUs that
represent integers as floating point, but undesirable for GPUs with
native integer division instructions.
TGSI, for example, has UDIV/IDIV instructions for integer division,
so it makes sense to handle this directly. Likewise for i965.

This DP4 had one of its operands missing, so we were generating

Set ctx->WindowRenderBuffer to EGL_BACK_BUFFER. As EGL_WINDOW_BIT of a
config is set only when there is dri_double_buffer, that makes sure
window surfaces are always double-buffered and contexts will render to
the back buffer.

Advertising different format support based on sample count was a
bad idea, it made resolve to window work, but resolve to anything
else would fail.

By emitting code before generate_code(), we ended up in align1 mode
where writemasks don't exist, so we rescaled gl_Vertex.w and things
went badly. By moving GL_FIXED support to the visitor, we end up with
normal codegen, and as a bonus the GL_FIXED setup ends up getting
printed appropriately in debug output.

At some point we need to also move uniform accesses out to pull

This avoids the massive conditional move array access, and brings code
generation quality for the new VS backend into the realm of efficiency
of the old backend (roughly 20% more instructions generated than
before across shader-db, instead of assertion failing for generating
over 10,000 instructions on many shaders!).

We sometimes want to put an instruction somewhere besides the end of
the instruction stream, and we also want per-opcode instruction
generation to enable compile-time checking of operands.
We'll be using that to track things for the new VS backend, and this will
avoid cluttering brw_vs_surface_state.c for it.

We were primarily failing to convert in the NativeIntegers case, which
this fixes. However, we were also just truncating float uniforms when
converting to integer, which does not appear to be the correct
behavior. Note, however, that the NVIDIA drivers also truncate
instead of rounding.
GL_DOUBLE return type is dropped because it was never used and
completely broken. It can be added when there's test code.

v2: This is a rewrite of my previous glGetUniform patch, which Ken

At least for Intel, all our uniform components are of uint32_t size, either
float or signed or unsigned int. For uploading uniform data in the driver,
it's much easier to upload a full dword per uniform element instead of trying
to pick out the bool byte and then fill in the top 3 bytes of pad with 0.
