There's a few minor mistakes in the old license statement, for
instance:
- missing the year 2014 from the copyright
- "without limitation the" instead of "without limitation on the"
Apart from that it's just minor details like wrapping, and adding
"(including the next paragraph)". None of this seems to change
anything from a legal standpoint.
This matches the copyright-header we have for the same file in
Mesa, and makes it a bit less noisy to update the file there.

When a texture is bound in its original form then the swizzle states and
the sRGB state were updated and if a texture view of this texture was bound
later it was assumed that the state is already submitted. However, it seems
that a texture view has its own, separate state that must be set separately,
so keep track of it on a per-view basis.

If a shader uses TGSI_INTERPOLATE_LOC_SAMPLE, we need to emit
the "sample"-keyword for the input-variable in the fragment
shader.
Since the "sampler"-keyword is a GLSL 4.00 feature, this
requires us to enable GL_ARB_gpu_shader5. Unfortunately, opting
in carefully on this is a bit trickier than for most other
extensions, because we patch up vertex, geometry or tesselation
evaluation shader outputs to match the fragment shader inputs.
Since the previous patch adds padding for the require-statement
directly after the #version string, we can just overwrite that
padding with the require statement.

This adds the renderer support for exposing texture views.
The change adds support to sampler views and surfaces for the backing
object to be a separately allocated textureview instead of the actual
resource. It also adds support for parsing the updated packet where
we put the sampler view target in the top 8 bits of the format,
which should be safe as up until now it's always 0.
This doesn't do the final enable of the extension, but it will
cause us to use views in a few places we didn't before so could have
some other side effects
v2: check for buffers on surface creation, reword comment
to better explain if statement.
v3: fix logic bug (Gert). This uncovered a wierd corner case, possibly
due to how the state tracker allocates textures, but it tries to create
a surface with more layers than there are, I think it then reallocate
the whole texture object in the guest and it works out in the end,
this adds check to catch this, and to avoid creating a texture view
in that case.
v4: realise the problem with v3 was 3D textures and use
util_max_layer to fix the logic properly.
