Now that the i965 backend doesn't depend on this field we can
make it more generic and short circuit a bunch of code paths.
The new field will be used in a following patch for another
clean-up.

This makes much more sense and should be more performant in some
critical paths such as SSO validation which is called at draw time.
Previously the CurrentProgram array could have contained multiple
pointers to the same struct which was confusing and we would often
need to fish out the information we were really after from the
gl_program anyway.
Also it was error prone to depend on the _LinkedShader array for
programs in current use because a failed linking attempt will lose
the infomation about the current program in use which is still
valid.
V2: fix validate_io() to compare linked_stages rather than the
consumer and producer to decide if we are looking at inward
facing shader interfaces which don't need validation.

To avoid build regressions the following 2 patches were squashed in to
this commit:
mesa/meta: rewrite _mesa_shader_program_use() and _mesa_program_use()
These are rewritten to do what the function name suggests, that is
_mesa_shader_program_use() sets the use of all stage and
_mesa_program_use() sets the use of a single stage.

mesa: update active relinked program
This likely fixes a subroutine bug were
_mesa_shader_program_init_subroutine_defaults() would never have been
called for the relinked program as we previously just set
_NEW_PROGRAM as dirty and never called the _mesa_use* functions when
linking.

We also move NumProgramResourceList at the same time.
GLES does interface validation on SSO at runtime so we need to move
this to be able to switch to storing gl_program pointers in
CurrentProgram.

This will help allow us to store gl_program in the CurrentProgram array rather
than gl_shader_program which will allow a bunch of simplifications.
Note that we make LinkedTransformFeedback a pointer so we don't waste
memory creating a struct for each stage. We also store a pointer to
the gl_program that will contain the pointer in gl_shader_program so
we can get easy access to the correct stage.

This fixes 555 dEQP tests (using the nougat-cts-dev branch), Piglit's
arb_program_interface_query/arb_program_interface_query-resource-query,
and GL45-CTS.program_interface_query.separate-programs-{tess-control,
tess-eval,geometry}. Only one dEQP program interface failure remains.
I would have liked to split this up into several distinct changes, but
I wasn't sure how to do that given thet tangled nature of these issues.
So, the issues:
* We need to treat interface blocks declared as an array of instances
as a single block - removing the outer array. The resource list
entry's name should not include the array length. Properties such
as GL_ARRAY_SIZE should refer to the variable inside the block, not
the interface block's array properties.
* We need to do this prefixing even for structure variables.
* We need to do this for built-ins (such as gl_PerVertex.gl_Position).
* After interface array unwrapping, any variable which is an array
should have [0] appended. It doesn't matter if it's a TCS/TES/GS
input or TCS output - that looked like an attempt to unwrap for
per-vertex variables, but that didn't consider per-patch variables,
and as far as I can tell there's nothing to justify this.
Several Mesa developers have suggested that Issue 16 contradicts the
main specification, but I believe that it doesn't - the main spec just
isn't terribly clear. The main ARB_program_interface query spec says:
"* For an active interface block not declared as an array of block
instances, a single entry will be generated, using the block name from
the shader source.
* For an active interface block declared as an array of instances,
separate entries will be generated for each active instance. The name
of the instance is formed by concatenating the block name, the "["
character, an integer identifying the instance number, and the "]"
character."
Issue 16 says that built-ins should be named "gl_PerVertex.gl_Position",
but several people suggested the second bullet above means that it
should be named "gl_PerVertex[array length].gl_Position".
There are two important things to note. Those bullet points say
"an active interface block", while the others say "variable" or "active
shader storage block member". They also don't mention applying the
rules recursively (unlike the other bullets). Both suggest that
these rules apply to blocks themselves, not members of blocks.
In fact, for GL_UNIFORM_BLOCK queries, we do have "block[0]",
"block[1]", ... resource list entries - so those rules are real,
and actually used. So if they don't apply to block members, then how
should members be named? Unfortunately, I don't see any rules outside
of issue 16 - where the rationale is very unclear. I hope to clarify
the spec in the future.

There are two distinctly different uses of this struct. The first
is to store GL shader objects. The second is to store information
about a shader stage thats been linked.
The two uses actually share few fields and there is clearly confusion
about their use. For example the linked shaders map one to one with
a program so can simply be destroyed along with the program. However
previously we were calling reference counting on the linked shaders.
We were also creating linked shaders with a name even though it
is always 0 and called the driver version of the _mesa_new_shader()
function unnecessarily for GL shader objects.

With SSO, the GL_PROGRAM_INPUT and GL_PROGRAM_OUTPUT interfaces refer to
the first and last shader stage linked into a program. This may not be
the vertex and fragment shader stages.
So, subtracting VERT_ATTRIB_GENERIC0 and FRAG_RESULT_DATA0 is bogus.
We need to subtract VERT_ATTRIB_GENERIC0 for VS inputs,
FRAG_RESULT_DATA0 for FS outputs, and VARYING_SLOT_VAR0 for other cases.

Patch makes following changes for interface matching:
- do not try to match builtin variables
- handle swizzle in input name, as example 'a.z' should
match with 'a'
- add matching by location
- check that amount of inputs and outputs matches
These changes make interface matching tests to work in:
ES31-CTS.sepshaderobjs.StateInteraction
The test still does not pass completely due to errors in rendering
output. IMO this is unrelated to interface matching.
Note that type matching is not done due to varying packing which
changes type of variable, this can be added later on. Preferably
when we have quicker way to iterate resources and have a complete
list of all existed varyings (before packing) available.
v2: add spec reference, return true on desktop since we do not
have failing cases for it, inputs and outputs amount do not
need to match on desktop.
v3: add some more spec reference, remove desktop specifics since
not used for now on desktop, add match by location qualifier,
rename input_stage and output_stage as producer and consumer
as suggested by Timothy.

If we have a dmat2[4], then dmat2[0] is at 17, dmat2[1] at 19,
dmat2[2] at 21 etc. The old code was returning 17,18,19.
I think this code is also wrong for float matricies as well.
There is now a piglit for the float case.
This partly fixes:
GL41-CTS.vertex_attrib_64bit.limits_test
[airlied: update with Tapani suggestion to clean it up].

This function is unfinished there is a bunch more validation rules
that need to be applied here. We will still want to call it for desktop
GL we just don't want to validate precision so move the ES check to

ARB_explicit_uniform_location allows the index for subroutine functions
to be explicitly set in the shader.
This patch reduces the restriction on the index qualifier in
validate_layout_qualifiers() to allow it to be applied to subroutines
and adds the new subroutine qualifier validation to ast_function::hir().
ast_fully_specified_type::has_qualifiers() is updated to allow the
index qualifier on subroutine functions when explicit uniform locations
is available.
A new check is added to ast_type_qualifier::merge_qualifier() to stop
multiple function qualifiers from being defied, before this patch this
would cause a segfault.
Finally a new variable is added to ir_function_signature to store the
index. This value is validated and the non explicit values assigned in
link_assign_subroutine_types().

Currently, these arrays in gl_shader and gl_shader_program hold both
UBOs and SSBOs, so this looks like a better name. We were already
using NumBufferInterfaceBlocks in gl_shader_program, so this makes
things more consistent as well.
In a later patch we will add {Num}UniformBlocks and
{Num}ShaderStorageBlocks which will contain only references to
UBOs and SSBOs respectively that will provide backends with
a separate index space for both types of objects.

For the property ARRAY_SIZE, a single integer identifying the number of
active array elements of an active variable is written to <params>. The
array size returned is in units of the type associated with the property
TYPE. For active variables not corresponding to an array of basic types,
the value one is written to <params>. If the variable is a shader
storage block member in an array with no declared size, the value zero
is written to <params>.
