* krb5_decode.c (begin_structure): Update to deal with indefinite

	* krb5_decode.c (begin_structure): Update to deal with indefinite
	encodings better; also call asn1_get_sequence().

	* asn1_k_decode.c (sequence_of): Update to deal with indefinite
	encodings better.
	(begin_structure): Update to deal with indefinite encodings
	better; also call asn1_get_sequence().

	* asn1_get.h: Update prototypes for asn1_get_tag_indef(),
	asn1_get_tag(), asn1_get_sequence(), asn1_get_length().

	* asn1_get.c (asn1_get_tag_indef): New function; get tag info,
	lengths, etc. as well as flag indicating whether the length is
	indefinite.
	(asn1_get_tag): Modify to just call asn1_get_tag_indef().
	(asn1_get_sequence): Call asn1_get_tag_indef() in order to
	determine whether encoding is indefinite length.
	(asn1_get_length): Add "indef" arg to indicate whether an encoding
	has an indefinite length.

	* asn1buf.h: Update asn1buf_imbed() prototype.

	* asn1buf.c (asn1buf_imbed): Add "indef" arg so that we don't
	treat a definite zero-length encoding as an indefinite encoding.
