23e77c5619 messaging: Avoid crashes
With the latest patches we defer messages to a messaging_context's default
context, the one that it was created with. This is another incarnation of
085542fc93 (I believe): messaging contexts can outlive their tevent contexts.

In this case, the tevent_schedule_immediate(msg_ctx->event_ctx) has nothing to
schedule on and will crash. This patch uses the fact that tevent_fd's can
outlive their event_contexts. When the tevent_context dies, all tevent_fd's
will get their flags set to 0. The tevent_handles in messages_dgm_ref always
have TEVENT_FD_READ set, so a 0 flags field indicates the tevent_context has
died.

1a3d081c99 pthreadpool_pipe: Implement EBUSY for _destroy
Restore EBUSY on pthreadpool_pipe_destroy.

We need to count jobs in pthreadpool_pipe so that pthreadpool can exit with
active jobs. Unfortunately this makes pthreadpool_pipe_add_job non-threadsafe.
We could add mutexes around "num_jobs", but this would mean another set of
pthread_atfork functions. As we don't use threaded pthreadpool_pipe_add_job
except in the tests, just remove the tests...

pthreadpool_destroy does not have to wait for the idle threads to finish, it

the last active thread will actually free(pthreadpool).
