    ifconfig(8): Sync with FreeBSD a bit and various cleanups
    
    * Sync ifconfig.c a bit with FreeBSD; replace several warnx() with
      errx(), and improve error messages a bit.
    
    * Remove unnecessary exit() after Perror().
    
    * Sync if_clone.c with FreeBSD.
    
    * Add inclusion guard to ifconfig.h.
    
    * Make iseq() a static function for ifieee80211.c and regdomain.c,
      replacing the duplicate definitions of it; and use iseq()
      consistently to replace strncasecmp() and strcasecmp().
    
    * Move "struct ident" from regdomain.c to regdomain.h, and add and use
      "enum IdentType".
    
    * Various whitespace cleanups.
    
    * Cleanup header file inclusion: remove duplicates, and reorder a bit.
    
    * Fix various signed vs. unsigned comparisons.
    
    * Fix some compilation warnings, and raise WARNS to 3.
