Add implementations of the two API functions,
Add a new strings to uint mapping for index bindings
Add the blending mode validation for SRC1 + SRC_ALPHA_SATURATE
Add get for MAX_DUAL_SOURCE_DRAW_BUFFERS
v2:
Add check in valid_to_render to address case in spec ERRORS.
v3:
Add index to ir.h so this patch compiles on its own
fixup comment
v4: fixup Brian's comments
The GLSL patch will setup the indices.

Page 77 (page 91 of the PDF) says about glGetActiveAttrib:
"The returned attribute name can be the name of a generic
attribute or a conventional attribute (which begin with the prefix
"gl_", see the OpenGL Shading Language specification for a
complete list)."
Page 261 (page 275 of the PDF) says about glGetProgramiv:
"If pname is ACTIVE_ATTRIBUTES, the number of active attributes in
program is returned."
It doesn't say anything about built-in vs. user-defined attributes.
From the language around glGetActiveAttrib and the lack of an
exclusion of built-in attributes, which exists other places (e.g.,
around glBindAttribLocation), we can infer that GL_ACTIVE_ATTRIBUTES
should include the active attribute count. It should also be included
in the values returned by glGetActiveAttrib.

Instead of relying on the mirror in the Mesa IR assembly shader, just
use the variables actually stored in the GLSL IR. This will be a bit
slower, but nobody cares about the performance of glGetActiveAttrib.

This just folds get_active_attrib into _mesa_GetActiveAttribARB
and moves the resulting function function to the other source file.
More changes are coming soon.

This currently mirrors the state tracking
gl_shader_program::Attributes, but I'm working towards eliminating
that.

This allows querying the linked shader itself rather than the Mesa IR.
This is the first step towards removing gl_program::Attributes.
