	* kstream-des.c (decrypt): if protect_rlogin_oob is set, detect
	that the MSB of the length is non-zero and assume that it is
	"lost" out-of-band data (and skip it.
	(_kstream_des_debug_OOB): if set, print out any skipped data for
	the user.

	* kstream-des.c (do_encrypt): Handle arbitrary sizes up to 16
	bytes with padding, so rlogin works.
	(encrypt): Pass chunks up to 16 bytes without fragmenting.
	(decrypt): Test assertion that the size of the incoming packet is
	no larger than our buffer size.

	* kstream.c: Include errno.h.
	(errno): Declare it.
	(kstream_read): If insufficient space is available, set errno to
	ENOMEM, and print a message if DEBUG is defined.  If reading from
	the net fails, and DEBUG is defined, call perror.
