Victor Julien 296ce8b5f9 file-data: make bytejump, bytetest, byteextract and isdataat work better with file_data. 14 years ago
Victor Julien 07e560b137 file-data: initial file_data support
Support file_data for: content, pcre (relative), byte_test, byte_jump,
byte_extract, isdataat.

File_data support is handled at signature parsing time, all matches
occurring after the file_data in the rule are converted to http_server_body
matches.

Content matches relative to the file_data are converted. Within to depth,
distance to offset. Relative to the start of the body buffer.

Victor Julien 89f83e714c 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.
