asn1_k_decode.c (setup, next_tag, apptag, get_field_body,
	get_lenfield_body, asn1_decode_ticket): Use the taglength to
	determine whether or not the indefinite encoding was used, and
	if so skip over the termination flag bytes in the ASN.1
	stream.

asn1buf.c (asn1buf_imbed, asn1buf_remains): Make changes to allow for
	indefinite encodings.  asn1buf_remains() is now only used for
	decoding structures and arrays (i.e., asn.1 constructs which
	terminate indefinite encodings with two zero octets.

	[ Note these fixes to support indefinite encoding aren't
	terribly clean; some invalid encodings may be accepted when they
	should not be.  This should be looked at in more detail later.]

asn1_get.c (asn1_get_tag): Inline original asn1buf_remains() code,
	since asn1_get_tag doesn't use asn1buf_remains in the context of
	a structure or an array.
