No functional changes.

2f48008c42 implement merging for top-k.
I am not (entirely) sure that this is mathematically correct, but
I am (more and more) getting the feeling that it... might be.

In any case - this was the last step and now it should work
in cluster settings.

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
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.

641154f8e8 FileAnalysis: checkpoint in middle of big reorganization.
- 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.

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.
