subject: Make gss_krb5_set_allowable_enctypes work for the acceptor
target_version: 1.9.1
tags: pullup

With the addition of enctype negotiation in 1.7, a gss-krb5 acceptor
can choose an enctype for the acceptor subkey other than the one in
the keytab.  If the resulting security context will be exported and
re-imported by another gss-krb5 implementation (such as one in the
kernel), the acceptor needs a way to restrict the set of negotiated
enctypes to those supported by the other implementation.  We had that
functionality for the initiator already in the form of
gss_krb5_set_allowable_enctypes; this change makes it work for the
acceptor as well.
