In various versions of OpenGL and GLSL, it's possible to declare
multiple VS input variables with aliasing attribute locations.
So, when computing the storage requirements for vertex attributes,
we can't simply add up the sizes. Instead, we need to look at the
enabled slots.
This patch begins tracking which attributes are double types that
are larger than 128-bits (i.e. take up two vec4 slots). We then
count normal attributes once, and count the double-size attributes
a second time.
Fixes deQP functional.attribute_location.bind_aliasing.max_cond_* tests
on i965, which regressed with commit ad208d975a.
No Piglit changes on llvmpipe (which actually supports dvecs).

This reverts commit c2ff3485b3.
Ilia and I noticed a memory leak caused by this patch: at least with
fixed-function programs, we clone things using ProgramResourceList as
the context before reralloc makes it non-NULL.
I believe Tapani found other bugs with these patches, so I'm just going
to revert them for now and let him pursue them further.
This increases memory pressure during linking but makes it easier
for backend to free IR after it is not needed anymore.

over-sized UBOs, but at least for llvmpipe receiving a UBO larger than
its limit causes problems, as it won't fit into its internal display
lists.
This fixes piglit "arb_uniform_buffer_object-maxuniformblocksize
fsexceed" without regressions for llvmpipe.
NVIDIA driver also fails to link the shader from
"arb_uniform_buffer_object-maxuniformblocksize fsexceed".

PS: I don't recommend cherry-picking this for Mesa stable, as some app
might inadvertently been relying on UBOs larger than
GL_MAX_UNIFORM_BLOCK_SIZE to work on other drivers, so even if this
commit is universally accepted it's probably best to let it mature in
master for a while.

This change introduces a new field in gl_uniform_storage to
explicitely say that a uniform is built-in. In the case where it is,
no storage is defined to make it clear that it is read-only from the
mesa side. I fixed all the places in the code that made use of the
structure that I changed. Any place making a wrong assumption and using
the storage straight away will just crash.
This patch seems to implement the path of least resistance towards
listing built-in uniforms in GL_ACTIVE_UNIFORM (and other APIs).

`interface` is a define on Windows -- an alias for `struct` keyword,
used when declaring COM interfaces in C or C++.
So use instead `programInterface`, therefore matching the name used
in GL_ARB_program_interface_query spec/headers, which was renamed exactly
for the same reason:
"Revision 10, May 10, 2012 (pbrown)
- Rename the formal parameter <interface> used by the functions in this
extension to <programInterface>. Certain versions of the Microsoft
C/C++ compiler and/or its headers cause "interface" to be treated as a
reserved keyword."
Trivial.
Patch adds ProgramResourceList to gl_shader_program structure.
List contains references to active program resources and is
constructed during linking phase.
This list will be used by follow-up patches to implement hooks
for GL_ARB_program_interface_query. It can be also used to
implement any of the older shader program query APIs.
