 Subject: Include authenticator and ticket authdata in gss-api
 ticket: 6400
 Target_version: 1.7
 Tags: pullup

 Currently, the GSS-API routines for handling authdata only extract the
 authorization data from the ticket, not that from the authenticator.
 This is incorrect.  Introduce a new function krb5_merge_authadata to
 merge two authdata arrays into a newly allocated result array.  Use
 this function in accept_sec_context.c to include both sets of
 authdata.
