If more then one input variable is tagged as requiring winsys_adjust_y then
this variable would be declared more then once and consequently compiling the
shader would fail.
Keep track of whether the variable was already declared to make sure it is emitted

When changing the from a one-by-one upload to an array upload the test for the
array pointer to the uniform IDs was replaced by testing the uniform array ID
against -1. However, this is not enough, because when the context is allocated
all is cleared to zero, and apparently the structure is re-used in different
invocations of shader programs. Here, one shader might have been removed but
the const field was still allocated resulting in a sigsegv. This happens e.g.
by running
dEQP-GLES31.functional.primitive_bounding_box.wide_points.
global_state.vertex_tessellation_geometry_fragment.fbo_bbox_larger

The sub-context holds a pointer to the last shader program used and this
is de-referenced , e.g. in vrend_vbo_draw. However, the guest may destroy
the program without notifying the sub-context, and as a result the pointer
becomes stale and may ber used after free.
As a solution add a pointer to the owning context when a program is
referenced and if the program gets destroyed, clean the pointer in the sub-context.

Not all compressed formats can be uploaded using glTexImage2D, that
only works if the extension provides an online texture-compressor. For
instance, EXT_texture_compression_s3tc only requires an online
compressor in the desktop version.
This test isn't really a test for the presence of an online-compressor,
this code is meant to test if we can render from it. But calling
glCompressedTexImage2D requires us to provide a valid compressed
payload, which is really awkward to maintain.
So let's instead just check for extensions to decide if these formats
are renderable or not.
Also, none of these compressed formats can be rendered to, so there's
no point in even testing for that.
Combined with a commit in mesa that enables EXT_texture_compression_s3tc
