If the client sends vrend_transfer_send_readpixels a stride (and vtest does),
then it is in bytes, but glPixelStorei(GL_PACK_ROW_LENGTH, stride) expects
the value to be pixels.

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

These VREND_BIND_*-flags here are basically a subset of the

This copy of the bind-flags should not be used, as they are a duplicate
set of what can already be found in virgl_hw.h.
But to avoid breaking theoretical, unknown users, we shouldn't remove
them either. So let's just add a comment to tell people not to use
them.

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.

TGSI has a different model for precise than GLSL, so we have to mark
all outputs that has gotten an precise operation output to it as
precise.
This only implements part of the 'precise' keyword (still lacking
support on individual operations), but it's enough to pass some dEQP
tests, in particular:
- dEQP-GLES31.functional.tessellation.common_edge.triangles_equal_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.triangles_fractional_odd_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.triangles_fractional_even_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.quads_equal_spacing_precise
- dEQP-GLES31.functional.tessellation.common_edge.quads_fractional_odd_spacing_precise

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.
