When guest mesa does a glReadPixel call, it expects the data to be placed
with correct row strides into the readback buffer. While for calls that
invert or require more then one IOV this is done in write_transfer_data,
for a read that only uses a small area and offset making it fit into the
first IOV this was not done. Consequently, in this case configure the
PACK_ROW_LENGTH accordingly.
v2: fix whitespace issues
This fixes a number of piglits:
arb_copy_image-targets (for texture_2d source or dest, non-compressed)
arb_get_texture_multisample/sample_position
arb_texture_rectangle/fbo-blit rect
arb_get_texture__sub_image-cubemap

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.

OpenGL ES 3.1 does not have glPrimitiveRestart; only OpenGL 3.1

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

Otherwise, it'd be possible to generate evil commands from a rouge
guest-driver that can crash the VM.
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.
v2: do not set have_gl_conditional_render if on GLES 3.0 or above.

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.
This fixes a number of tests from the subset
dEQP-GLES31.functional.copy_image.non_compressed.viewclass_*
v2: - Clean list of canonical formats (Gurchetan Singh)
- Use size of canonical formats to decide whether they can be copied via
gCopyImageSubData
- Also honour the render state when deciding whether glCopyImageSubData
will do, or whether we need to do a blit.
v3: - replace format size check by compatibility check (Gurchetan Singh) but
keep the check seperate because we need to add logic for compressed
texture later

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.
