imessaging_client_init() can be used with a wrapper tevent_context,
but only if a global messaging_dgm_ref() already exist.
All other uses of imessaging_init() and imessaging_client_init()
require a raw tevent_context.

In usecases like using messaging_client_init() with irpc processing we may
free the imessaging_context during the messaging handler.
imessaging_post_handler() is not yet really used, but it will change in
the next commits. imessaging_post_state is a child of imessaging_context
and might be implicitly free'ed before the explicit TALLOC_FREE(state).

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.

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.

This replaces the transport mechanism in source4 with calls to the

lock directory, source4 does not have a cache directory.

According to python docs, PyArg_ParseTuple takes "int" and "unsigned
long long". With pointers down to functions, in particular with
varargs, there is no automatic conversion. So we need to be very
strict about types. Automatic conversion to for example uint64_t
happes only with assignment.
