mesa optimizes away the information about input layouts for generics and
patches for TCS, TES, and GEOM shaders (all that pass these inputs as
arrays), but when input arrays are allowed, then these varyings may
actually have overlapping layouts (at least some piglits do, even though
they don't specifically require ARB_enhanced_layouts).
To be able to link shaders like these with enables arrays pass this info
to the next stage.

Arrays of arrays are way easier to handle and they are available on GLES

path is still able to use blocks for passing parameters to and from

Since TGSI is vector based it passes clip and cull distances as
values or arrays of vec4 values, but the glsl shader wants to access it
as arrays of scalars. To work around this handle the FS input just like
the outputs, i.e. introduce an array of temporaries vec4 and copy the
data there.
For all other shader types the access to the values only needs to take
account of the possibility of indirect adressing or an array offset.

When we enable indiviudal IO arrays that are passed from the host we
will no longer generate the one big array, but we know only after all
declarations have been parsed, whether the guest emitted these arrays or
whether we have indirect access to elements but no arrays so that we
need to build them. So do this array generation after parsing the
declarations.
v2: - If available use the output ranges size of the previous shader when
defining the input range for the generated arrays, mesa might have
optimized away some individual values.
- Add a GLSL version requirement when an interface block will be created.

for GLES, with the exception of the TCS->TES out->in, where arrays of

When calling vrend_renderer_transfer_write_iov through
vrend_renderer_transfer_iov, we sometimes come down these
code-paths with the context 0 active, but the non-zero context being
passed as the context-pointer. Trying to do any caching based on this
will only lead to incorrect behavior.
There's little point in trying to fixup the caching in the ctx0 for
this call-site, as there's no other code-path using ctx0 that tries
to play ball with the cache.
So let's get rid ot the context-argument when possible, and pass a
NULL-pointer when it can come either from ctx0 or a rendering-context.
