... and also improved the test suite. There is a design issue in the
v3 queue engine that manifested to some serious problems with the new
processing mode. However, in v3 shutdown may take eternally if a queue
runs in DA mode, is configured to preserve data AND the action fails and
retries immediately. There is no cure available for v3, it would
require doing much of the work we have done on the new engine. The window
of exposure, as one might guess from the description, is very small. That
is probably the reason why we have not seen it in practice.

so far, the last processed message was only freed when the next
one was processed. This has been changed now. More precisely, a
better algorithm has been selected for the queue worker process, which
also involves less overhead than the previous one. The fix for
"free last processed message" as then more or less a side-effect
(easy to do) of the new algorithm.

... needed to split the old single counter into two. I wouldn't bet that
I made some mistakes while doing so, but at least some ad-hoc tests plus
the testbench do no longer indicate errors.

version does not really work, but is a good commit point. Next comes
queue size calculation. DA mode does not yet work.

So far, the consumer was responsible for destroying objects. However, this
does not work well with ultra-reliable queues. This is the first move to
support them.

as I am on the path to the final implementation.

an abort.

... plus a fix for a long-time bug in obj-types.h. That lead to
the object pointer only then to become NULL when the object was
actually destructed, I discovered this issue during
introduction of the pRcvFrom property in msg_t, but it potentially had other
effects, too. I am not sure if some experienced instability resulted from this
bug OR if its fix will cause harm to so-far "correctly" running code. The later
may very well be. Thus I will change it only for the current branch and also
the beta, but not in all old builds. Let's see how things evolve.

some things inside the message can be used over a large number of
messages and need to to be allocated and re-written every time. I now
begin to implement this as a "prop_t" object, first use for the inputName.
Some input modules are already converted, some others to go. Will do
a little performance check on the new method before I go further.
Also, this commit has some cleanup and a few bug fixes that prevented
compiliation in debug mode (I overlooked this as I did not compile
for debug, what I normally do, and the automatted test also does not
do that)

- bugfix: subtle (and usually irrelevant) issue in timout processing
timeout could be one second too early if nanoseconds wrapped
- set a more sensible timeout for shutdow, now 1.5 seconds to complete
processing (this also removes those cases where the shutdown message
was not written because the termination happened before it)
