While i915 does have hardware contexts in hardware, we don't expect there
to ever be SW support for it (given that support hasn't even made it back
to gen5 or gen4).

Every driver left in Mesa that enables one also enables the other.
There's no reason to let it be optional.

In Mesa, this extension is implemented purely in software. Drivers may
*optionally* provide optimized paths. If a driver enables,
GL_ARB_texture_multisample, it gets GL_ARB_texture_storage_multisample
for free.
NOTE: This has the side effect of enabling the extension in Gallium
drivers that enable GL_ARB_texture_multisample.
v2 (Ken): Still prevent multisample texture targets in TexParameter for
implementations that don't support multisampling.

This extension just provides some of the most basic software framework
for GLSL. Without GL_ARB_vertex_shader or GL_ARB_fragment_shader,
applications still cannot use GLSL. There's no value in
conditionalizing support for this extension.

brw_wm_surface_state.c has gotten rather large and unwieldy. At this
point, it consists of two separate portions:
1. Surface format code
This includes the giant table of surface formats and what features
they support on each generation, as well as the code to translate
between Mesa formats and hardware formats.
This is used across all generations.
2. Binding table (SURFACE_STATE) related code.
This is the code to generate SURFACE_STATE entries for renderbuffers,
textures, transform feedback buffers, constant buffers, and so on, as
well as the code to assemble them into binding tables.
This is only used on Gen4-6; gen7_surface_state.c has Gen7+ code.
Since the two are logically separate, and one is reused on every
generation while the other is not, it makes a lot of sense to split
them out. It should also make finding code easier.
No code is changed by this patch. I simply copied the file then deleted
portions of both.
