mesa: Make _mesa_GetActiveAttribARB use the attributes in the shader IR
Instead of relying on the mirror in the Mesa IR assembly shader, just
use the variables actually stored in the GLSL IR. This will be a bit
slower, but nobody cares about the performance of glGetActiveAttrib.

mesa: Move _mesa_GetActiveAttribARB to shader_query.cpp
This just folds get_active_attrib into _mesa_GetActiveAttribARB
and moves the resulting function function to the other source file.
More changes are coming soon.

mesa: Move _mesa_GetAttribLocationARB to shader_query.cpp
This allows querying the linked shader itself rather than the Mesa IR.
This is the first step towards removing gl_program::Attributes.

The symbol table in the linked shaders may contain references to
variables that were removed (e.g., unused uniforms). Since it may
contain junk, there is no possible valid use. Delete it and set the
pointer to NULL.

mesa: Remove ARB_draw_buffers extension enable flag
All drivers in Mesa have supported this extension for eons. This
extension is an optional features in desktop OpenGL (via
GL_ARB_draw_buffers) and OpenGL ES 2.x (via GL_NV_draw_buffers).
The extension is not usable in OpenGL ES 1.x. There is no
glDrawBuffers* entry point in OpenGL ES 1.x contexts, and glGet*v
generate errors when MAX_DRAW_BUFFERS or DRAW_BUFFERi is queried.

swrast: When asked to map a slice of a 1D array, give back that slice.
Until now, we've been treating 1D arrays as a single slice, and each
array slice is actually just a row of the 2D texture. While swrast
still stores them this way, hardware drivers think that 1D arrays have
actual separate slices not stored as contiguous rows.

intel: Consolidate texture validation copy code, and reuse it correctly.
The path for ->Data was failing to be called for the FBO draw offset
fallback, and also had mismatched compressed texture support code.
This drops the intel_prepare_render() in the blit path. We aren't
copying to/from a GL_FRONT buffer, so it doesn't matter.
intel: Clean up the function chain for mapping texture images for swrast.
Too many separate functions each called from one location (in
different files). This code should all die soon when swrast starts
using MapTextureImage.
intel: Allocate s8z24 separate renderbuffers from AllocTextureImageBuffer().
Before, we were only allocating these from our TexImage, so if the
texture image was set up in any other way (non-accelerated
glGenerateMipmaps()), they'd be missing or wrong.
