We should avoid traversing a linked list within a thread without holding

Using a mutex would be very tricky as we'll likely deadlock with

In the direction from the main process to the job thread, we have:
- 'maycancel', which is set when tevent_req_cancel() is called,
- 'orphaned' is the job request, tevent_context or pthreadpool_tevent
was talloc_free'ed.
The job function can consume these by using:
/*
* return true - if tevent_req_cancel() was called.
*/
bool pthreadpool_tevent_current_job_canceled(void);
/*
* return true - if talloc_free() was called on the job request,
* tevent_context or pthreadpool_tevent.
*/
bool pthreadpool_tevent_current_job_orphaned(void);
/*
* return true if canceled and orphaned are both false.
*/
bool pthreadpool_tevent_current_job_continue(void);
In the other direction we remember the following points
in the job execution:
- 'started' - set when the job is picked up by a worker thread
- 'executed' - set once the job function returned.
- 'finished' - set when pthreadpool_tevent_job_signal() is entered
- 'dropped' - set when pthreadpool_tevent_job_signal() leaves with orphaned
- 'signaled' - set when pthreadpool_tevent_job_signal() leaves normal
There're only one side writing each element,
either the main process or the job thread.
This means we can do the coordination with a full memory
barrier using atomic_thread_fence(memory_order_seq_cst).
lib/replace provides fallbacks if C11 stdatomic.h is not available.
A real pthreadpool requires pthread and atomic_thread_fence() (or an
replacement) to be available, otherwise we only have pthreadpool_sync.c.
But this should not make a real difference, as at least
__sync_synchronize() is availabe since 2005 in gcc.
We also require __thread which is available since 2002.

ldb attributes are either bytes (py3) or str (py2)
Some places in the code do str(res[0]['attribute'][0])
which results in
'result' (py2)
b'result' (py3)
or more commonly the attribute is used to construct a string e.g.
"blah=" + res[0]['attribute'][0] + ",foo,bar=...."
giving
"blah=result,foo,bar=...." (py2)
and very unhelpfully
"blah=b'result',foo,bar=...." (py3)
lots of code already constructs various strings for passing to other
api using the above. To avoid many excessive
res[0]['attribute'][0].decode('utf8')
code like 'res[0]['attribute'][0]'
will now return LdbBytes (a new object subclassing 'bytes') in py3
instead of bytes. This object has a custom '__str__' method which
attempts to return a string decoded to uft8. In Py2 this will behave as
it did previously (this is the safer option at the moment)

requires to use send() instead of sendto().

Add an adjustment to the before and after values to cater for the
occasional differences between the calculated times.
The exact value of the time stamp is not important what is important is
that is correctly formatted and that the value is reasonable i.e. it's
close enough to the current time.

Instead, we either build or do not build the entire binary.
This is much more likely to raise an error in make test if the build system
changes. The concern is that HAVE_JANSSON can go away and the tests just vanish.

When no search filter is specified, the code falls back to using
'(|(objectClass=*)(distinguishedName=*)'. ltdb_index_dn() then failed
because matching against '*' is not indexed. The error return then
caused the code to fallback to a full-scan of the DB, which could have a
considerable performance hit.
Instead, we want to continue on and do the ltdb_index_filter() over the
indexed results that were returned.
