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.
v2: use lowercase enum, move debug_cb in as well.
rename tf2, sort list.

Otherwise, it'd be possible to generate evil commands from a rouge

This is a bit trickier than the previous one, because we were already
mixing calls to the OpenGL 3.0 version and the GL_NV_conditional_render
version, which indicates that this was previously only safe if *both*
were supported, that is OpenGL 3.0 *with* GL_NV_conditional_render.
Now, this code should match the caps we generate, which shouldn't give
any percieved feature-regressions or gl-versions supported.

When the host is gles >= 3.2, gl >= 4.3, or when the extension
GL_(ARB|EXT|OES)_copy_image is available, memcopy like blitting and region
copying can be done for many color format combinations by using
glCopyImageSubData.

v2: - Clean list of canonical formats (Gurchetan Singh)

gCopyImageSubData
- Also honour the render state when deciding whether glCopyImageSubData
will do, or whether we need to do a blit.

later it was assumed that the state is already submitted. However, it seems

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.

In the copy fallback, when a texture can not be rendered, the data that resides
in the backing iovec needs to be used. For the non-zero levels of mip-map textures
the data is located at an offset. This patch adds storing this offset and using it
when data is read from the backing iovec and updating the dst iov. We limit the
mip-map levels for which this is done to 1-17, which is enough to cover
32kx32k textures. The patch also fixes the stride when accessing mip-map levels.
