Update to 1.33, as requested in pkg/16254.
Changes:
    Added make file options for SCO and NetBSD.  The Makefile has been
    reconfigured a touch to make it clearer what needs to be done for each
    OS.

    Turn was accepting invalid option as in heyu turn allaskljas.  It now
    complains and exits.

    Found bug in scanning the macros. (thanks to David Pointer)

    Dan Eble reported a bug (or feature) that allows chaining macros
    with delays.  I've fixed the bug but not enabled the feature.

    Makesched utility created.  This utility pre-preocesses a file in the
    x10sched format and sends a revised version to standard output with the
    strings "dawn" and "dusk" expanded to appropriate values.

    Cleaned up some error messages to give feedback when the locks fail.

    A coding error was causing the dates in the schedule loader to be off
    in some cases.  Thanks to Charles Sullivan for finding and reporting
    the bug and it's fix

    The use of just the -v option caused a sigfault.  The errant code
    was corrected in x10.c main().
