39444b5af7 Moved DPD signatures into script specific directories.
- This caused us to lose signatures for POP3 and Bittorrent.  These will
   need discovered in the repository again when we add scripts
   for those analyzers.

cdf6b7864e More file analysis updates.
- Recorrected the module name to Files.

  - Added Files::analyzer_name to get a more readable name for a
    file analyzer.

  - Improved and just overall better handled multipart mime
    transfers in HTTP and SMTP.  HTTP now has orig_fuids and resp_fuids
    log fields since multiple "files" can be transferred with
    multipart mime in a single request/response pair.  SMTP has
    an fuids field which has file unique IDs for all parts
    transferred. FTP and IRC have a log field named fuid added
    because only a single file can be transferred per irc and ftp
    log line.

- One obvious downside is that queued logs at termination may not
    get logged because the trigger for the when statement never matches.

705a84d688 Improve tracking of HTTP file extraction (addresses #988).
http.log now has files taken from request and response bodies in
different fields for each, and can now track multiple files per body.
That is, the "extraction_file" field is now "extracted_request_files"
and "extracted_response_files".

Part of this involves making the file-analysis tests independent of
specific hash values. I've done that only partially though.

ae9a02140e Fix the issue with transaction ID reuse in a single DNS connection.
- Each transaction ID within a connection is now maintained as
   a queue of DNS::Info logging records.

 - New function added to the queue.bro script to support
   peeking at the new gettable item in the queue without removing it.

would be. Not all tests pass yet though (and file hashes have changed
unfortunately).

037d582b0e FileAnalysis: add custom libmagic database.
- It's derived from the magic database of libmagic 5.14, but with most
  everything not related to mime types removed.

- The custom database is always used by default for mime detection, but
  the more verbose file type detection will fall back on the default
  libmagic installation's database.  The result is: mime type strings
  are now guaranteed to be consistent across platforms, but the verbose
  file type descriptions are not.

- The custom database gets installed in $prefix/share/bro/magic, and
  should even be extensible if files with new patterns are added inside
  the directory.

- The search path for the mime magic database can be controlled via
  BROMAGIC environment variable.

- Remove mime_desc field from ftp.log.

- Stop using the mime/file type canonifier with unit tests.

- libmagic >= 5.04 is now a requirement.

2747e839fb FileAnalysis: insert explicit event queue flush points.
And added an event called "event_queue_flush_point" to mark where that

flush instead of buffering input in order to wait for a file handle to
be returned from script-layer.

- Starting to transfer policy hook triggers and analyzer results to

fc267d010d FileAnalysis: optimize get_file_handle event queueing.
When a file handle is needed and the last event in the queue is also
a get_file_handle event with the same arguments, instead of queueing
a new event, just remember to cache/re-use the resulting handle from
the previous event.  This depends on get_file_handle handlers not
changing global state that is also used to derive the file handle
string.
