Made some class templates for code that seemed duplicated between
file/protocol tags and managers. Seems like it helps a bit and
hopefully can be also be used to transition other things that have
enum value "tags" (e.g. logging writers, input readers) to the
plugin system.
This cleans up internals of how analyzer instances get identified by the
tag plus any args given to it and doesn't change script code a user
would write.
* origin/topic/seth/faf-updates: (27 commits)
Undoing the FTP tests I updated earlier.
Update the last two btest FAF tests.
File analysis fixes and test updates.
Fix a bug with getting analyzer tags.
A few test updates.
Some tests work now (at least they all don't fail anymore!)
Forgot a file.
Added protocol description functions that provide a super compressed log representation.
Fix a bug where orig file information in http wasn't working right.
Added mime types to http.log
Clean up queued but unused file_over_new_connections event args.
Add jar files to the default MHR lookups.
Adding CAB files for MHR checking.
Improve malware hash registry script.
Fix a small issue with finding smtp entities.
Added support for files to the notice framework.
Make the custom libmagic database a git submodule.
Add an is_orig parameter to file_over_new_connection event.
Make magic for emitting application/msword mime type less strict.
Disable more libmagic builtin checks that override the magic database.

- Fix examples/references in the file analysis how-to/usage doc.
- Add Broxygen-generated docs for file analyzer plugins.
- Break FTP::Info type declaration out in to its own file to get
rid of some circular dependencies (between s/b/p/ftp/main and
s/b/p/ftp/utils).
in.
No more manual includes to pull them in.
(It doesn't quite work fully automatically yet for some bifs that need
script-level types defined, like the input and logging frameworks.
They still do a manual "@load foo.bif" in their main.bro to get the
order right. It's a bit tricky to fix that and would probably need
splitting main.bro into two parts; not sure that's worth it.)
- 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.
- 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.
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).

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.
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.
- FileAnalysis::Info is now just a record used for logging, the fa_file
record type is defined in init-bare.bro as the analogue to a
connection record.
- Starting to transfer policy hook triggers and analyzer results to
events.
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.
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.
