Parsing HTTP CONNECT to extract the tunnel IP and port information.
Alerting and dechunking for chunked encoding in HTTP1.0 request and response.
Fixed an issue where, if we have a junk line before HTTP response header, the header was wrongly parsed.
Fixed GZIP evasions where an HTTP response with content-encoding:gzip contains a body that has a GZIP-related anomaly.
Fixed an issue in certain scenarios where a BitTorrent pattern is seen only on the third packet of the session, causing us to miss our client detection.
SMB improvements for file detection and processing.

- Release 126.96.36.199-1
* Added support to block portscan. In addition to tracking the scanning packets, action(drop/sdrop/reject) will be taken for all the packets,
which means Snort will block the packet and generate logs.
* Added support to re-evaluate reputation after reputation update for all flows except those that have already been blacklisted.
* Fixed issue to detect RTP up to two SSRC switches in each traffic direction.
* Fixed issues related to HTTP POST header flushing, calling file processing directly if it is not a multipart header and changes to avoid expensive
copy of segment data by not splitting them when flushing headers.
* Fixed issue of triggering protocol sweep alert when there are multiple destinations from single source ip protocol scan.
* Added changes to fix IP portscan for protocol other than ICMP and fixed issue of bad fragment size event not being generated for oversized packets.
* Added changes to use raw data in case of PDF and SWF files during file processing for SHA calculation and Malware Cloud Lookup.
* Fixed issue of correct session matching for TCP SYN packets without window scale option so that FTP data channels match the same rule as FTP control channels.
* Fixed issue of applying new configuration in file inspection after Snort reload.
