Utility wrapper around icalparser.
* cal-util/cal-util.c (cal_util_parse_ics_file): Utility wrapper around icalparser. * cal-util/test-recur.c (main): Use it * pcs/cal-backend-file.c (open_cal): Likewise * gui/comp-editor-factory.c (open_client): Add the OpenClient to the hash before calling cal_client_open_calendar, since in some failure cases, that will call cal_opened_cb (which will free the oc) with a failure immediately, causing a crash if we then try to deref it. svn path=/trunk/; revision=20492
