new file -- things shared between the client and server go in this

        * cal-util/Makefile.am: new file -- things shared between
        the client and server go in this directory

        *  calobj.c calobj.h icalendar.c icalendar.h
        timeutil.c timeutil.h cal-util.c cal-util.h where moved
        backend stuff went into pcs.  shared stuff went into
        cal-util.
