state_tracker/st_program.c: In function 'st_print_shaders':

i965: Make FS uniforms be the actual type of the uniform at upload time.
This fixes some insanity that would otherwise be required for GLSL
1.30 bit ops or gen6 integer uniform operations in general, at the
cost of upload-time pain. Given that we only have that pain because
mesa's mangling our integer uniforms to be floats, this something that
should be fixed outside of the shader codegen.
First, it changes autoconf to use a "python2" binary when available,
rather than plain "python" (which is ambiguous). Secondly, it changes
the Makefiles to use $(PYTHON) $(PYTHON_FLAGS) rather than calling
python directly.

radeon_bo_destroy() will want to read the list field. Without this patch,
we'd end up evaluating the list pointers before they have been properly
set up when we destroyed the newly created bo if it cannot be mapped.

mesa: call _mesa_valid_to_render() in glDrawPixels, glCopyPixels, glBitmap
This lets us simplify and consolidate some state checking code.
This implements the GL_INVALID_OPERATION check for all drawing commands
required by GL_EXT_texture_integer.
i965: Add support for discard instructions on gen6.
It's a little more painful than before because we don't have the handy
mask register any more, and have to make do with cooking up a value
out of the flag register.
i965: Use SENDC on the first render target write on gen6.
This is apparently required, as the thread will be initiated while it
still has dependencies, and this is what waits for those to be
resolved before writing color.
