radeon: Remove the loop from stride size calculation.
Changed stride size calculation to do the math by rounding
the value instead of loop. r600 minimum stride is 256 which
might might cause up to about 60 rounds of the loop.
i965: Keep the CURBE BO mapped and memcpy instead of subdataing.
For the tiny bis of data we generally upload through the CURBEs, the
overhead of the kernel's pagetable trickery is actually rather high.
This improves cairo-gl gnome-terminal-vim performance by 3.8%.
st/mesa: allow negative index for PROGRAM_STATE_VAR
The piglit vp-address-01 test uses negative address-relative
offsets. In this test we're indexing into PROGRAM_STATE_VAR
which, in turn, contains references to ENV vars.
We previously fixed this issue for PROGRAM_CONSTANT.
piglit/vp-address-01 (the version from Feb 5) passes now.

osmesa: Add OSMesaColorClamp and OSMesaGetProcAddress to symbol defs.
Without this patch, the two symbols get an underscore prepended
and an "@4" appended when compiling with VC8.

This fixes the progs/glsl/pointcoord.c demo. But this isn't a proper fix.
We really need a TGSI_SEMANTIC_POINT_COORD label so that the draw module
can determine which fragment input / vertex output slot needs to be set
up with the point coordinate info. We've been using generic slot 0 so far.
This would also require telling the draw module about fragment shaders
(something it doesn't have at this time).
tgsi: remove special-case code for fragment position
Since the origin_lower_left / pixel_center_origin changes, we need
to use the fragcoord info that's set up in setup_fragcoord_coeff().
The code in exec_declaration() was clobbering the the interpolated
fragment position.
Fixes progs/glsl/fragcoord.c demo.
egl_xdri steals code from src/glx/x11/. This makes it broken from time
to time when there is a bigger change to the GLX code. As egl_dri2 has
been merged, which also functions as a DRI2 driver loader, remove
egl_xdri for good.
Both a link and a binding creates a reference to the resource. Drivers
should not destroy the resource when there is a reference. The
difference is better described in doc/egl.html.
mesa: change ctx->Driver.ProgramStringNotify() to return GLboolean
GL_TRUE indicates that the driver accepts the program.
GL_FALSE indicates the program can't be compiled/translated by the
driver for some reason (too many resources used, etc).
Propogate this result up to the GL API: set GL_INVALID_OPERATION
error if glProgramString() was called. Set shader program link
status to GL_FALSE if glLinkProgram() was called.
At this point, drivers still don't do any program checking and
always return GL_TRUE.
