0c4346e632 intel: disable ATI_texture_env_combine3 for i830( and related device). 
Thanks to Eric for pointing it out.

6c01500228 dri: Fix driWaitForMSC32 when divisor >= 2 and msc < 0. 
We'd come up with a negative remainder, while we were looking for the positive
version of it in the loop conditional.  And, since the "did we hit our target"
break was disabled for the target_msc == 0 ("Just make the divisor/remainder
work") path, we'd never exit.

Simplify the code by just using int64_t all over instead of trying to do it
in a u32 space.

129b6bc4e3 i915: separate the fog term from the specular color term. 
Previously fog parameter and specular color are packed into the
same dword. Note specular color should be packed in BGRA for device,
so if fog parameter and specular color all are present, fog parameter
will dirty the alpha term of specular color. This fixes rendering
issue when playing 'Yo Frankie' on 915/945.

f83f5ec8f5 Add do_row_3d for mipmapping 3D textures 
Previously 3D textures were mipmapped using multiple passed through
the 2D mipmap generation code.  This had 3 disadvantages.  First, the
extra passes were slow.  Second, this required the allocation of a
temporary buffer to hold intermediate data.  Third, and most
important, the extra passes caused loss of additional bits due to
integer division / bit-shifting.

With this change, our mipmapgen conformance test passes for
non-compressed texture formats.

7e04272690 965 / GLSL: Use full precision for EXP instruction

962fa6bbc1 GLSL: The LOG2 macro doesn't have enough precision 
It looks like the LOG2 macro only has 8 or 9 bits of precission, but
the ARB_vertex_program spec says "accurate to at least 10 bits".

1e7785fe07 intel: Move copyteximage source clipping out of copytexsubimage. 
glCopyTexSubImage already gets the (correct) clipping for us, so it doesn't
need the path.  While moving the clipping out, replace the code with the mesa
path to do the same job.

aa09e0a1d5 mesa: Correct _mesa_clip_to_region() off-by-one. 
Note how if:
x + width == xmax + 0: width -= 0
x + width == xmax + 1: width -= 0
x + width == xmax + 2: width -= 1

So, the function was clipping to [xmin, xmax+1), not [xmin, xmax) like it was
supposed to.  Same for ymax.

1126aa86bf Perform range checking on app supplied texture base level 
It is possible for applications to specify any texture base level,
including trivially invalid values (i.e., 47000000).  When an app
specifies an invalide base level, we should gracefully disable the
texture instead of accessing memory outside the gl_texture_object.

This fixes an occasional segfault in one of our conformance tests.
