Now depth is kept in mind when we inspect chunks in client/server body.
This takes care of FPs originating from inspecting subsequent chunks that
match with depth, but shouldn't.
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.
In some cases AppLayerTransactionGetInspectId can return -1, which is
now handled by all it's callers.
Improve logic of selecting which transactions are inspected by the various
HTTP keywords.
Introduce a separate FlowAddress structure for holding the ipv4 or ipv6 address
that doesn't have the family in it like the Address structure. Instead, the
family is stored in the flow as a flag: FLOW_IPV4 and FLOW_IPV6.
Add macro's to check the family, copy the address, etc.
Update many unittests to reflect these changes. Introduce unittest helper
functions for creating and initializing a flow and freeing it again.
On 64 bit this shrinks the flow with 8 bytes.
Removal of per flow 'aldata' array. It contained a ptr for each ALPROTO. Instead now we have 2 ptrs in the flow: alparser and alstate.
Various cleanups and dead code removal from the app layer API.
Should safe 100+ bytes memory per flow on 64 bit.
Updated lots of unittests to reflect these changes.
