    macros2: Deprecate GNOME_MAINTAINER_MODE_DEFINES
    
    The modules which it deprecates are all ancient and unused. Many of the
    modules which use GNOME_MAINTAINER_MODE_DEFINES don’t make use of the
    DISABLE_DEPRECATED variable it generates anyway.
    
    If a module really wants maintainer mode, they should use
    AM_MAINTAINER_MODE. Otherwise, they should just eliminate this call
    entirely.
