* main.c: Move kdc_initialize_rcache() to kdc_util.c

	* main.c: Move kdc_initialize_rcache() to kdc_util.c

	* kdc_util.c (kdc_initialize_rcache): Move kdc_initialize_rcache()
	back here since it's needed for rtest to work.  process_tgs_req()
	which is called from rtest needs to call kdc_intiialize_rcache()
	and we can't very well link rtest with main.o

	* kdc_preauth.c (verify_sam_response): Ooops.  Get rc_lifetime
	from kdc_util, since it's actually declared there.
