    calendar(1): Sync with FreeBSD
    
    New features:
    * Support events that span multiple years, because of '-A', '-B' or just
      the three days before the end of the year.
    * Support for lunar events (full moon, new moon), solar events (equinox,
      solstice), and Chinese new year.  Because of this, the options '-U'
      (UTC offset) and '-l' (longitude) are available to compensate if
      reality doesn't match the calculated values.
    * Implement an internal 'cpp'-like parser to parse the calendars, so no
      longer require the external cpp(1).
    
    Changed behavior:
    DragonFly's calendar(1) switched to use the 'calendar.all' file by
    default in 9abdd9620822cc1232dc702a76d95ebf133733b5.  This calendar file
    always exists.  However, it makes calendar(1) print too much entries,
    which I think most users would not need.  So switch to the original
    default calendar file, i.e., 'calendar', the same as other BSDs.
    
    The following minor changes were made:
    1. In 'calendar.c' and 'io.c', delete the unused 'copyright' variable
       to suppress the compilation warnings.
    2. In 'sunpos.c', rename the macro 'MIN(h)' to 'MINUTE(h)' to avoid the
       conflict; meanwhile rename the macro 'SMIN(h)' to 'SMINUTE(h)' for
       better consistency.
    
    More cleanups and improvements to follow.
