... seems to work on quick testing, but needs a far more testing
and improvement. Good milestone commit.

... hopefully reducing the number of allocs/frees as well as overall
memory usage in a busy system (plus that these shared properties hopefully
remain in cache longer than its single-instance counterparts...)

This sets stage to enable use of the property-interface to speed
up things (mildly), the next step to be done. I have also fixed one
regression of yesterday's changes.

... 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.

... plus some celanup and adding minor missing functionality
(the rule debug info again tell the property name, not just number).

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)
