Instead of having the features in separate named bool, convert it
to an array of bools indexed by an enum.
This is a straight mechanical patch, no code flows should change
and it doesn't change any functionality, it just refactors the
code to use the enum list and a bool array.
Future work should be a lot easier on this, so I'd like to
land it first.

TGSI has a different model for precise than GLSL, so we have to mark

precise.

Three component formats are not very helpful, at least the Intel driver doesn't

them using RGBX textur formats. RGB32* we have to keep though because it is needed
for ARB_rbo_rgb32 which in turn is needed for OpenGL 4.0.

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.

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.
