We want to set GENSEC_FEATURE_SIGN and GENSEC_FEATURE_SEAL based on the given
auth_level and should not have GENSEC_FEATURE_SEAL if
DCERPC_AUTH_LEVEL_INTEGRITY is desired.

source4/rpc_server/dcerpc_server.c:dcesrv_request() calls gensec_have_feature().
Codenomicon found a code path that allows the client to send a
request that calls into this function without ever having set
up security. So call->conn->auth_state.gensec_security exists
(gensec has been initialized when the RPC pipe is set up)
but call->conn->auth_state.gensec_security->ops has not been
initialized. We dereference the NULL pointer and crash.
An alternate way to fix this would be to create a new
public bool gensec_initialized(() function and call that
inside dcesrv_request() instead of doing a null
check on call->conn->auth_state.gensec_security,
but that's a more invasive fix we can add later.

Even with CRED_MUST_USE_KERBEROS we should keep the DCERPC_AUTH_TYPE_SCHANNEL
backend arround, this can only be specified explicitely by the caller
and cli_credentials_get_netlogon_creds() != NULL is the strong indication
that the caller is using DCERPC_AUTH_TYPE_SCHANNEL *now*.
With trusts against AD domain we can reliable use kerberos and netlogon
secure channel for authentication.

This is the current gensec_update() which takes an optional
tevent_context structure and allows semi-async code.
This is just a temporary solution on the way to kill
the semi-async code completely, by using gensec_update_send/recv.
By providing a gensec_update_ev(), we can remove the explicit
tevent_context from gensec_update() and fix all the sane callers.

In future we should remove the tevent_context argument from
gensec_update() completely!
If we have sane backends we should also remove the
tevent_loop_allow_nesting() call again!
