    a11y: Remove AtkStreamableContent implementation
    
    That is some old code that still uses IOChannels, and the only
    pseudouser is at-spi-atk's commented out code that is still using
    CORBA types.
    
    So get rid of it now before I need to start adapting it to the new
    clipboard.
