For consistency, ./configure generated "config.h" must be the first
header include through out the project.

in which debug output can be generated only after the process has started,
but not right from the beginning. This is assumed to be useful for
hard-to-find bugs. Also improved the doc on the debug system.
support for enhancing probability of memory addressing failure by
using non-NULL default value for malloced memory (optional, only if
requested by configure option). This helps to track down some
otherwise undetected issues within the testbench and is expected
to be very useful in the future.
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.
to make sure only the minimum number of file handles is left open
during a exec call. This is not a 100% solution, as there are also
some fopen() calls and, more importantly, file descriptors opened
by libraries. But it is better than nothing (and it was quick, at
least until we run into platform hell, what we will for sure ;)).
There exists a race condition that can lead to a segfault. Thanks
go to vbernetr, who performed the analysis and provided patch, which
I only tweaked a very little bit.
there are still some files left which could go into the
runtime, but I think we will delete most of them once we
are done with the full modularization.
I commented out some debug code that is only useful in some
testing scenarios and re-enabled the old code. This solved a FreeBSD
compile issue. Also, I fixed some other syntax error, which somehow
went into the tree (I am still puzzled about that, especially as some
have already and successfully build from that tree... anyhow ;)).
