    mesa: Disallow deprecated SNORM formats for renderbuffers
    
    The OpenGL 3.2 core profile spec says:
    
        "The following base internal formats from table 3.11 are
        color-renderable: RED, RG, RGB, and RGBA. The sized internal formats
        from table 3.12 that have a color-renderable base internal format
        are also color-renderable. No other formats, including compressed
        internal formats, are color-renderable."
    
    The OpenGL 3.2 compatibility profile spec says (only ALPHA is added):
    
        "The following base internal formats from table 3.16 are
        color-renderable: ALPHA, RED, RG, RGB, and RGBA. The sized internal formats
        from table 3.17 that have a color-renderable base internal format
        are also color-renderable. No other formats, including compressed
        internal formats, are color-renderable."
    
    Table 3.12 in the core profile spec and table 3.17 in the compatibility
    profile spec list SNORM formats as having a base internal format of RED,
    RG, RGB, or RGBA.  From this we infer that they should also be color
    renderable.
    
    The OpenGL ES 3.0 spec says:
    
        "An internal format is color-renderable if it is one of the formats
        from table 3.12 noted as color-renderable or if it is unsized format
        RGBA or RGB. No other formats, including compressed internal
        formats, are color-renderable."
    
    In the OpenGL ES 3.0 spec, none of the SNORM formats have "color-
    renderable" marked in table 3.12.  The RGB I and UI formats also are not
    color-renderable in ES3, but we'll save that change for another patch.
    
    Both NVIDIA's closed-source driver (version 304.64) and AMD's
    closed-source driver (Catalyst 12.6 on HD 3650) reject *all* SNORM
    formats for renderbuffers in OpenGL 3.3 compatibility profiles.
    
    v2: Move {RED,RG,RGB,RGBA}_SNORM changes from the this commit to the
    next commit.  Based on suggestions from Ken.
