    mesa: Add error checking in _mesa_BlitFramebuffer() for MRTs
    
    This patch adds required error checking in _mesa_BlitFramebuffer() when
    blitting to multiple color render targets. It also fixes a case when
    blitting to a framebuffer with renderbuffer/texture attached to
    GL_COLOR_ATTACHMENT{i} (where i!=0). Earlier it skips color blitting if
    nothing is found attached to GL_COLOR_ATTACHMENT0.
    
    V2: Fixed a case when number of draw buffer attachments are zero.
    V3: Do compatible_color_datatypes() and compatible_resolve_formats()
        check for all the draw renderbuffers in fbobject.c. Fix debug code
        at bottom of _mesa_BlitFramebuffer() to handle MRTs. Combine error
        checking code for linear blits with other color blit error checking.
