Formats a KRB_SAFE message into outbuf.
userdata is formatted as the user data in the message.
sumtype specifies the encryption type; key specifies the key which
might be used to seed the checksum; sender_addr and recv_addr specify
the full addresses (host and port) of the sender and receiver.
The host portion of sender_addr is used to form the addresses used in the
KRB_SAFE message.
The outbuf buffer storage is allocated, and should be freed by the
caller when finished.
