mesa: Rewrite the way uniforms are tracked and handled
Switch all of the code in ir_to_mesa, st_glsl_to_tgsi, glUniform*,
glGetUniform, glGetUniformLocation, and glGetActiveUniforms to use the
gl_uniform_storage structures in the gl_shader_program.
A couple of notes:
* Like most rewrite-the-world patches, this should be reviewed by
applying the patch and examining the modified functions.
* This leaves a lot of dead code around in linker.cpp and
uniform_query.cpp. This will be deleted in the next patches.
v2: Update the comment block (previously a FINISHME) in _mesa_uniform
about generating GL_INVALID_VALUE when an out-of-range sampler index
is specified.
