remove contribution from mono_matsuko

we could not reach him to agree to the re-licensing to ASL 2.0.
So I remove his contribution, which means we do no longer need
has agreement. This was the original contribution:

http://git.adiscon.com/?p=rsyslog.git;a=commitdiff;h=fb7fab511e0de2566c0de47468b443ef5bb508d3

Note that the bug is now introduced again. We will fix it via a
different method in the next commit.
make rsyslogd -v output work in regard to 64 bit atomic buildin info
place some more code under ASL 2.0

Note:

* Yann Droneaud contribution to this code has been removed
  with this commit
* mono_matsuko contribution was already removed by previous
  commits

The rest was my own code.
