Split stream reassembly in 2 parts: a part that sends ack'd data to the app
layer parsers as soon as it's available, and another part that queues up
data into larger chunks for raw inspection.
Stateful detection for app layer detection keywords, except uricontent. Stores it's partial results in the flow structure. Other modifications:
- Generalize transaction tracking, logging and inspection.
- Adapt http and dcerpc to use the new transaction handling.
- Stream engine now always notifies app layer of a stream eof.
This commit fixes bug #124.
- improve locking of application layer handling, making sure that the flow cannot be freed/cleared when the detection engine is still working with it.
- add a check to the app layer detection to make sure that a match function will only inspect an app layer state if it's of the right type.
