Accept GSS mechs which don't supply attributes If gss_inquire_attrs_for_mech() is called for a mechanism which does not implement it, the call will succeed with mech_attrs set to GSS_C_NO_OID_SET (as is explicitly allowed by RFC 5587). generic_gss_test_oid_set_member() returns an error on this value, causing gss_accept_sec_context() to erroneously deny the mechanism when no verifier credential handle is supplied. Change allow_mech_by_default() to explicitly check for no mech attribute set.
