OpenGL ES didn't support GL_POINT_SPRITE_COORD_ORIGIN.
So when we read from a fbo, the image is upside down.
This is because the guest renders into a window drawable
which is inverted, while the host renders into a FBO.
This patch inverts the y coordinate.

Take into account the gallium uniform buffer indices when associating
host UBOs with gallium uniform buffers.
Previously the code disregarded the gallium uniform buffer indices,
leading, under specific circumstances, to the provision of incorrect
data to the shaders. The problem manifested typically when a context
contained active UBOs which were not accessed by a particular shader,
but ended up being used instead of the correct UBOs for that shader.
This occurred, for example, when running the dEQP-GLES3.functional.ubo.*
in batch mode, in which case left over UBOs from previous tests would
cause subsequent tests to fail.

The 'invariant' output data attrib was not properly implemented in
mesa's TGSI serialization, and was ignored in virglrender's conversion
from TGSI text to GLSL text. This patch adds 'invariant' support
and sets a new virgl cap to enable it since older versions of
virglrenderer will fail if invariant appears in the TGSI stream.

Previously, vrend_shader insterted a scale & bias to emulate
glDepthRange in all vertex shaders. This approach will fail
to match the gl spec in some situations. glDepthRange() is also
called, causing the transformation to be applied twice. The
winsys_adjust uniform is now a scalar to implement the y-flip only.
This bug was discovered and tested using the
dEQP-GLES2.functional.depth_range test suite. This test now passes
all but one case, which appears to be a separate issue.
