The fragment program native limits are actually higher on R4xx
as reported by Alex Deucher, but using those requires some
bit-twiddling changes to program handling.

Since 5a459d58fca2b71cb77c39f98df8a81ce6298421, libEGL no longer links
to libX11. Add the dependency to affected progs and cleanup
prog/egl/Makefile.

ARB prog: Change handling of program parameter limits
Several changes are made to program parameter limits. Several of the
non-NATIVE limits are set higher. All of the NATIVE limits are set to
zero in the core Mesa code. Each driver must set the actual value in
its context creation routine. If the NATIVE value remains zero, this
indicates that hardware shaders may not be supported.
Each of the preceeding changes matches the bahavior of Apple's shader
assembler, so it seems safe.
Finally, we limit the value of MaxEnvParams to be no greater than
MaxNativeAttribs. At least one case has been found where an
application does the wrong thing if MaxNativeAttribs < MaxEnvParams.
See also bugzilla #23490.
Only use the macro variant of MAD when absolutely necessary.
Apparently it cannot deal with relative addressing.

Find used temporaries even if they are only written to in dead code.
This fixes a bug in the NQSSADCE stage.

This is to allow a driver to drive multiple displays. Remove the use of
_EGL_PLATFORM_X and obsolete code along the way.

i965: fix incorrect tex unit in emit_tex() and emit_txb()
The instructions we're translating already went through the brw_wm_pass_fp()
function which does the sampler->texture unit mapping. We were applying
the sample->unit mapping a second time in the GLSL texture emitters.
Often, this made no difference but other times it could lead to accessing
an invalid texture and could cause a GPU lockup.
