	* cr_tkt.c: KRB4_PUT32 -> KRB4_PUT32BE.

	* decomp_tkt.c: krb_strnlen -> krb4int_strnlen.

	* g_ad_tkt.c: krb_strnlen -> krb4int_strnlen.  KRB4_PUT32 ->
	KRB4_PUT32BE.  Properly skip date while parsing error.

	* g_in_tkt.c: krb_strnlen -> krb4int_strnlen.  KRB4_PUT32 ->
	KRB4_PUT32BE.  Properly skip date while parsing error.

	* g_phost.c: Changes from audit.  Actually bail out instead of
	failing silently if h->h_name is too long.

	* kname_parse.c: Changes from audit.  Check overrun per character
	processed.

	* mk_auth.c: krb_strnlen -> krb4int_strnlen.  KRB4_PUT32 ->
	KRB4_PUT32BE.  Include prot.h.
