Initial import of KTH eBones. This has been cleaned up to only include

the "core" Kerberos functionality. The rest of the userland will get their
own changes later.

+/*
+ * This routine is called by the Kerberos authentication server
+ * to create a reply to an authentication request.  The routine
+ * takes the user's name, instance, and realm, the client's
+ * timestamp, the number of tickets, the user's key version
+ * number and the ciphertext containing the tickets themselves.
+ * It constructs a packet and returns a pointer to it.
+ *
+ * Notes: The packet returned by this routine is static.  Thus, if you
+ * intend to keep the result beyond the next call to this routine, you
+ * must copy it elsewhere.
+ *
+ * The packet is built in the following format:
+ * 
+ * 			variable
+ * type			or constant	   data
+ * ----			-----------	   ----
+ * 
+ * unsigned char	KRB_PROT_VERSION   protocol version number
+ * 
+ * unsigned char	AUTH_MSG_KDC_REPLY protocol message type
+ * 
+ * [least significant	HOST_BYTE_ORDER	   sender's (server's) byte
+ *  bit of above field]			   order
+ * 
+ * string		pname		   principal's name
+ * 
+ * string		pinst		   principal's instance
+ * 
+ * string		prealm		   principal's realm
+ * 
+ * unsigned long	time_ws		   client's timestamp
+ * 
+ * unsigned char	n		   number of tickets
+ * 
+ * unsigned long	x_date		   expiration date
