    TpfPersonaStore: make _supported_fields, _supported_fields_ro private
    
    Making them "internal" means we end up #include'ing small-set.h, which
    we don't install, so nothing can be built against the installed
    libfolks-telepathy. Nothing outside this file uses those members
    directly anyway.
