This is not a full fix yet as we don't allow compound requests

With SMB 3.11 requiring signed TreeConnect requests it's pointless
to try to compound requests after a SessionSetup.

The race is easily reproduced by adding a poll(NULL,0,10) in between the two
pthread_mutex_unlock calls in _tevent_threaded_schedule_immediate.
Before 1828011317, the main thread was signalled only after the helper
had already unlocked event_ctx_mutex.
Full explaination follows:
-----------------------------------------------------------------
Inside _tevent_threaded_schedule_immediate() we have:
476 ret = pthread_mutex_unlock(&ev->scheduled_mutex);
477 if (ret != 0) {
478 abort();
479 }
HERE!!!!
481 ret = pthread_mutex_unlock(&tctx->event_ctx_mutex);
482 if (ret != 0) {
483 abort();
484 }
At the HERE!!! point, what happens is tevent_common_threaded_activate_immediate(),
which is blocked on ev->scheduled_mutex, get released and does:
514 while (ev->scheduled_immediates != NULL) {
515 struct tevent_immediate *im = ev->scheduled_immediates;
516 DLIST_REMOVE(ev->scheduled_immediates, im);
517 DLIST_ADD_END(ev->immediate_events, im);
518 }
- making an immediate event ready to be scheduled.
This then returns into epoll_event_loop_once(), which then calls:
910 if (ev->immediate_events &&
911 tevent_common_loop_immediate(ev)) {
912 return 0;
913 }
which causes the immediate event to fire. This immediate
event is the pthread job terminate event, which was previously
set up in pthreadpool_tevent_job_signal() by:
198 if (state->tctx != NULL) {
199 /* with HAVE_PTHREAD */
200 tevent_threaded_schedule_immediate(state->tctx, state->im,
201 pthreadpool_tevent_job_done,
202 state);
So we now call pthreadpool_tevent_job_done() - which does:
225 TALLOC_FREE(state->tctx);
calling tevent_threaded_context_destructor():
384 ret = pthread_mutex_destroy(&tctx->event_ctx_mutex); <---------------- BOOM returns an error !
385 if (ret != 0) {
386 abort();
387 }
as we haven't gotten to line 481 above (the line after
HERE!!!!) so the tctx->event_ctx_mutex is still
locked when we try to destroy it.
So doing an additional:
ret = pthread_mutex_lock(&tctx->event_ctx_mutex);
ret = pthread_mutex_unlock(&tctx->event_ctx_mutex);
(error checking elided) forces tevent_threaded_context_destructor()
to wait until tctx->event_ctx_mutex is unlocked before it locks/unlocks
and then is guaranteed safe to destroy.

This makes the behaviour much more robust, particularly with forest child
domains over one-way forest trusts.
Sadly we don't support this kind of setup with our current ADDC, so
there's no way to have automated tests for this behaviour, but
at least we know it doesn't break any existing tests.

* Add efficient function to find duplicate values in ldb messages
(this makes large multi-valued attributes in ldb_tdb more efficient)
Signed-off-by: Douglas Bagnall <douglas.bagnall@catalyst.net.nz>
ldb backends need to make sure they are not adding duplicate values to
multi-valued attributes in ADD and MODIFY operations. Until now they
have done this inefficiently using nested loops. Here we add common
functions that deal with large numbers of values in O(n log n) time,
but continue to use the simple methods for small numbers of values.
These functions take a struct ldb_context pointer and an options flag
arguments, although the ldb is not used, and only one bit of the
options has meaning. This is to allow further patches to switch on
schema-aware comparisons.
This entails an ABI jump to add the two new functions.
