        Added get_phase_flags. The phase flags message contains the enabled/disabled
        flags for max_green2 and max_green3, which are needed to determine what
        the maximum green for a given time is.
        Added veryverbose and veryveryverbose flags
        Perfected phase sequence determination (for when init_spat and get_spat are separated)
        Added left arrows to SignalLightState. Still need to read them from MAP.
modified:   data_manager.c
        Removed cruft #includes at beginning of file
        Added forward port for TCI->SPAT_MAP_BCAST_INPORT
        Added mapping of inport numbers (known) to fd's (unknown at startup)
        Rectified confusion about MMITSS vs. non-MMITSS messages.  The latter
        are the polls sent by the TC, et al. for SPaT requests, etc.
