Transaction engine redesigned.

Browse Source 
Improved accuracy, improved performance.  Performance improvement
noticeable with http heavy traffic and ruleset.

A lot of other cosmetic changes carried out as well.  Wrappers introduced
for a lot of app layer functions.

Failing dce unittests disabled.  Will be reintroduced in the updated dce
engine.

Cross transaction matching taken care of.  FPs emanating from these
matches have now disappeared.  Double inspection of transactions taken
care of as well.
