simplified and thus speeded up the queue engine, also fixed some
potential race conditions (in very unusual shutdown conditions)
along the way. The threading model has seriously changes, so there may
be some regressions.
NOTE: the code passed basic tests, but there is still more work
and testing to be done. This commit should be treated with care.
... by moving code to stream.c. Thanks to the new design, new cases are
not really needed, resulting in cleaner code.
I also did a cleanup of header file usage as a side-activity.
... this was long overdue, and I finlly tackeld it. It turned out to
be more complex than I initially thought. The next step now probably is
to actually implement multiple rule sets and the beauty that comes
with them.
- added the ability to specify an error log function for the
runtime
- removed dependency of core runtime on dirty.h
Note that it is "better" modularity, not perfect. There is still
work to do, but I think we can for the time being proceed with
other things.
