    Fix several bugs relating to uniforms and attributes in GLSL API
    
    - fix sizes for GL_FLOAT_MAT2x3 and GL_FLOAT_MAT4x3 in sizeof_glsl_type
    - fix size returns in _mesa_get_active_attrib
    - fix out-of-bounds array access to vec_types in _mesa_get_active_attrib
    - fix queries of matrix uniforms in _mesa_get_uniformfv
    - fix _mesa_get_uniformfv to only return one base, even from an array
    - allow location == -1 in _mesa_uniform
    - validate types in _mesa_uniform
    - allow array overruns in _mesa_uniform
