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.

90fa331279 File analysis framework interface simplifications.
- Remove script-layer data input interface (will be managed directly
  by input framework later).

- Only track files internally by file id hash.  Chance of collision
  too small to justify also tracking unique file string.

4ccd6d76fd Fixing tests.
Part of this involves making the file-analysis tests independent of
specific hash values. I've done that only partially though.

eb637f9f3e Merge remote-tracking branch 'origin/master' into topic/robin/plugins
Thanks to git this merge was less troublesome that I was afraid it
would be. Not all tests pass yet though (and file hashes have changed
unfortunately).

0141f51801 FileAnalysis: load custom mime magic database just once.
This works around a bug in libmagic since version 5.12 (current at
time of writing is 5.14) -- second call to magic_load() w/ non-default
database segfaults.

2747e839fb FileAnalysis: insert explicit event queue flush points.
And added an event called "event_queue_flush_point" to mark where that
occured in the event stream.  The FAF now uses an explicit event queue
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

393d35dc60 Revert "FileAnalysis: optimize get_file_handle event queueing."
This reverts commit fc267d010d.

There were some diffs caused by this in external test suites I'm
unsure about, I'm going to go over optimizations more closely in
a different branch.

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.

3642ecc73e FileAnalysis: misc. tweaks/fixes.
- Add a timeout flag to file_analysis.log so it's easy to tell what
  has had at least one timeout trigger happen.

- Fix ftp-data service tag not being set for reused connections.

- Fix HTTP::Incorrect_File_Type because mime types returned by FAF have
  the charset still in them, but the HTTP::mime_types_extensions table
  does not and it requires an exact string match. (still ugly)

- Add TRIGGER_NEW_CONN to track files going over multiple connections.

- Add an initial file/mime type guess for non-linear file transfers.

- Fix a case where file/mime type detection would never be attempted
  if the start of the file was a content gap.

- Improve mime type tracking of HTTP byte-range/partial-content,
  even if the requests are pipelined or over multiple connections.

- I changed the modbus.events test because having the baseline output
  be 80+ MB is nuts and it was sensitive to connection record redefs.
