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.

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).
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.
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.
DEBUG preprocessor macro is set by configure script when
--enable-debug is passed for configure. Radeon then just
increase debugging verbosity if DEBUG is set in compile
time.
