Introduce http_server_body keyword.
...
The http_server_body content modifier modifies the previous content to inspect
the normalized (dechunked, unzipped) http_server_body. The workings are similar
to http_client_body. Additionally, a new pcre flag was introduced "/S".
To facilitate this change the signature flags field was changed to be 64 bit.

HTTP transaction handling improvement
...
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.

flow: shrink Flow datatype
...
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.

App Layer cleanup
...
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.

Always try PCRE_NO_AUTO_CAPTURE first for signature regexes.
...
Many, many pcre: signatures specify (...) when the more efficient
(?:...) is all that is needed. This change attempts to force
PCRE_NO_AUTO_CAPTURE on all unnamed capture groups, reverting to
capturing when necessary, e.g., when \1 is referenced.

First stab at creating a stateful detection engine.
...
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 .
