While the GL_ARB_stencil_texturing extension does not allow the creation
of stencil textures, it does allow shaders to sample stencil values
stored in packed depth/stencil textures.
Specifically, applications can call glTexParameter* with a pname of
GL_DEPTH_STENCIL_TEXTURE_MODE and value of either GL_DEPTH_COMPONENT or
GL_STENCIL_INDEX to select which component they wish to sample. The
default value is GL_DEPTH_COMPONENT (for traditional depth sampling).
Shaders should use an unsigned integer sampler (presumably usampler2D)
to access stencil data. Otherwise, results are undefined. Using shadow
samplers with GL_STENCIL_INDEX selected also is undefined behavior.
This patch creates a new gl_texture_object field, StencilSampling, to
indicate that stencil should be sampled rather than depth. (I chose to
use a boolean since I figured it would be more convenient for drivers.)
It also introduces the [Get]TexParameter code to get and set the value,
and of course the extension plumbing.
v2: Also consider textures incomplete when sampling stencil with
non-NEAREST min/mag filters (caught by Eric Anholt).

The code that checks if some texture target is valid for
glGetTexLevelParameter*() was not programmed to check for multisampling
proxy textures. This made it impossible(?) to use the proxy textures
for their intended purpose as glGetTexLevelParameter*() would just fail

GL_ARB_texture_multisample
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.

Adds the new texture targets, and per-image state for GL_TEXTURE_SAMPLES
and GL_TEXTURE_FIXED_SAMPLE_LOCATIONS.
V2: - Allow multisample texture targets in glInvalidateTexSubImage too.
This was already partly there, but I missed it the first time around
since the interaction is defined in a newer extension. Fixed weird
indentation.
- Allow multisample array textures in glFramebufferTextureLayer.
This was overlooked as the tests originally only used 2d
multisample textures.
V3: - Set min/mag filters sensibly for multisample textures. This
can't actually be changed by the user, so it's more sensible to
initialize it correctly than to hack around it being bogus later.
V4: - Tidy up initial min/mag filter setup. Setup in
_mesa_initialize_texture_object was bogus, but benign since
finish_texture_init() clobbered everything with correct values. For V4,
just do the setup in finish_texture_init().
V5: - Don't break glPopAttrib(GL_TEXTURE_BIT)

OpenGL 4.2 specification suggests rounding the float data to nearest
