Listing the GLSL version as an individual component of a GL version,
separate from the extensions isn't really right. The GLSL changes are
(almost?) entirely comprised of changes listed in the extensions.

Adds 0-3 textureGather component selection and non-constant offsets
Caveat: 0 and 1 texture swizzles only work if textureGather component
select is 3 or a component that does not exist in the sampler texture
format. This is a hardware limitation, any other value returns
128/255=0.501961 for both 0 and 1.
Passes all textureGather piglit tests on radeon 6670, except for those
using 0/1 texture swizzles due to aforementioned reason.

It turns out we can allow COHERENT storage/mappings all the time,
regardless of LLC vs non-LLC. It just means never using temporary
mappings to avoid GPU stalls, and on non-LLC we have to use the GTT intead
of CPU mappings. If we were to use CPU maps on non-LLC (which might be
useful if apps end up using buffer_storage on PBO reads, to avoid WC read
slowness), those would be PERSISTENT but not COHERENT, but doing that
would require us driving the clflushes from userspace somehow.

On earlier hardware, we had to implement math in the shader to translate
Y-tiled or untiled coordinates to W-tiled coordinates (which is what
BLORP does today in order to texture from stencil buffers).
On Broadwell, we can simply state that it's W-tiled in SURFACE_STATE,
and adjust the pitch. This is much easier.
In the surface state code, I chose to handle the "should we sample depth
or stencil?" question separately from the setup for sampling from
stencil. This should make it work with the BindRenderbufferTexImage
hook as well, and hopefully be reusable for GL_ARB_texture_stencil8
someday.
v2: Update docs/GL3.txt (caught by Matt).

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).

Almost every driver already supported it. All current and future
Gallium drivers always support it, and most existing classic drivers
support it.
This only changes radeon and nouveau.
This extension only adds data types that can be passed to, for example,
glTexImage2D. It does not add internal formats. Since you can already
pass GL_FLOAT to glTexImage2D this shouldn't pose any additional issues
with those drivers. Note that r200 and i915 already supported this
extension, and they don't support floating-point textures either.

The functions were broken, because they converted ints to floats.
Now we can finally advertise OpenGL 3.0. ;)
In this commit, the vbo module also tracks the type for each attrib
in addition to the size. It can be one of FLOAT, INT, UNSIGNED_INT.
The little ugliness is the vertex attribs are declared as floats even though
there may be integer values. The code just copies integer values into them
without any conversion.
This implementation passes the glVertexAttribI piglit test which I am going
to commit in piglit soon. The test covers vertex arrays, immediate mode and
display lists.
NOTE: This is a candidate for the stable branches.
