/*  Given d2i_-decoded asn1ticket, allocate and return a new krb5_ticket.
**  Return Kerberos error code and kssl_err struct on error.
**  Allocates krb5_ticket and krb5_principal; caller should free these.
**
**	20010410	VRS	Implemented krb5_decode_ticket() as
**				old_krb5_decode_ticket(). Missing from MIT1.0.6.
**	20010615	VRS 	Re-cast as openssl/asn1 d2i_*() functions.
**				Re-used some of the old krb5_decode_ticket()
**				code here.  This tkt should alloc/free just
**				like the real thing.
