On D-GL a program may contain a TE shader but no TC shader. On GLES either
both or none of TES and TCS need to be available. So if the guest sends a
shader program without a TCS, inject a passthrough shader using the
patch parameters given in the GL code.

When we add new feature checks on the host side that is used to enable
a cap conditionally in the guest that was enabled unconditionally before
we might end up with a feature regression when a new mesa version is
used with an old virglrenderer version that doesn't check for that cap.
To work around this problem add a version id to the caps that corresponds
to the features that are actually checked on the host so that it can be
checked in the guest whether this cap was actually checked for or whether
it should be enabled unconditionally.
The id should be incremented whenever a new feature check is added that
might result in a feature regression in the guest when run on an old host.

This avoids a potential race when multiple pipelines are running in
parallel and could update/overwrite the ':latest' tag.
For example, with two pipelines, A and B, the following could occur:
A1 -> build image and update :latest tag to digest DigestA
B1 -> build image and update :latest tag to digest DigestB
A2 -> use image from :latest tag assuming it's DigestA, but it's
actually DigestB
...
Explicitly using the image digest avoids the problem:
A1 -> build image with digest DigestA and update :latest tag
B1 -> build image with digest DigestB and update :latest tag
A2 -> use image with digest DigestA
B2 -> use image with digest DigestB

On GLES Mesa rejects arrays of arrays as TCS and TES shader inputs and outputs.
This is based on section 4.3 of the GLSL 3.20 ES standard where an error should be
produced for "Per-vertex-arrayed arrays of arrays" and "For non-per-vertex-arrayed
array of arrays", so apparently something like
in vec4 [][N];
is not allowed and on GLES interface blocks have to be used instead. In addition the
code needed some fixups when interface blocks are used.

The shaders are issued backwards starting from the fragment
shader and, therefore, in the first pass when we fill out
the shader keys for the TES no TCS will be present.
So don't bail out in this case and assume there is a VS.
Later, when the VS shader is compiled it will check whether
a TES is present without a TCS and report the error.

On GL WR translates to writable, but on GLES we translate this
to writeonly because for most formats one has to specify one or
the other, so if we have an image with the TGSI WR specification,
and read from it, we drop the Writable flag. For the images that
allow RW this is of no consequence, and for the others a write
access will fail instead of the read access, but this doesn't
constitue a regression because we couldn't do both - read and
write - anyway.
