[Tom Yu via RT]

Use public OID for interposing several functions

This resolves an issue where an interposer would receive the private
OID, and be unable to call back into krb5 in the expected manner in
gss_inquire_names_for_mech(), gss_inquire_cred_by_mech(),
gss_localname(), gss_store_cred(), and gss_store_cred_into().

Also change the return code of gss_localname() to GSS_S_BAD_MECH
instead of GSS_S_UNAVAILABLE on mech lookup failure, for consistency
with other functions.
