a120fb1c72 s4:messaging: add imessaging_init_discard_incoming()
We often create imessaging contexts just for sending messages,
but we'll never process incoming messages because a temporary event
context was used and we just queue a lot of imessaging_post_state
structures with immediate events.

With imessaging_init_discard_incoming() we'll discard any incoming messages
unless we have pending irpc requests.

8c75d9fc73 pymessaging: Add a hook to run the event loop, make callbacks practical
These change allow us to write a messaging server in python.

The previous ping_speed test did not actually test anything, so
we use .loop_once() to make it actually work.  To enable practial use
a context is supplied in the tuple with the callback, and the server_id
for the reply is not placed inside an additional tuple.

In order to get at the internal event context on which to loop, we
expose imessaging_context in messaging_internal.h and allow the python
bindings to use that header.

cfce21281a s4/messaging: messaging_dgm_ref talloc hierarchy fix
Ensure the messaging dgm context goes away *before* the tevent
context. The messaging dgm context will likely have active fd or timer
events, their rundown will touch the associated tevent context.

Otoh, I deliberately don't free the imessaging context here, that's going
to happen as part of freeing the talloc_autofree_context() as before. I
think it suffers the same problem, eg imessaging_deregister() works on
an imessaging_context that might already be freed. But as it works,
don't change it.
