d84f6e012c Fix various documentation, mostly related to file analysis.
- 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).

32f1c736f7 Some script reorg and a new intel extension script.
- policy/frameworks/intel/seen is the new location for the scripts
    that push data into the intel framework for checking.

  - The new policy/frameworks/intel/do_notice script adds an example
    mechanism for data driven notices.

939619889d File analysis fixes and test updates.
- Several places were just using old variable names or not loading
  scripts correctly after they'd been renamed/moved.

- Revert/adjust a change in how HTTP file handles are generated that
  broke partial content responses.

- Turn some libmagic builtin checks back on; seems some are actually
  useful (e.g. text detection seems to be a builtin).  The rule going
  forward probably will be only to turn off a builtin if we confirm it
  causes issues.

- Removed some tests that are redundant or not necessary anymore because
  the generic file analysis tests cover them.

- A couple FTP tests still fail that I think need an actual solution via
  script changes.

9b444b2617 Updates for the Intel Framework.
- Intel importing format has changed (refer to docs).

 - All string matching is now case insensitive.

 - SMTP intel script has been updated to extract email
   addresses correctly.

 - Small fix sneaking into the smtp base script to actually
   extract individual email addresses in the To: field
   correctly.

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.

  Streaming reads from external commands work without blocking anything.
  replace popen with fork and exec.

bec965b66f Large update for the SumStats framework.
- On-demand access to sumstats results through "return from"
   functions named SumStats::request and Sumstats::request_key.
   Both functions are tested in standalone and clustered modes.

 - $name field has returned to SumStats which simplifies cluster
   code and makes the on-demand access stuff possible.

 - Clustered results can only be collected for 1 minute from their
   time of creation now instead of time of last read.

 - Thresholds use doubles instead of counts everywhere now.

 - Calculation dependency resolution occurs at start up time now
   instead of doing it at observation time which provide a minor
   cpu performance improvement.  A new plugin registration mechanism
   was created to support this change.

 - AppStats now has a minimal doc string and is broken into hook-based
   plugins.

 - AppStats and traceroute detection added to local.bro

38ac03d558 Remove logging of analyzers field of FileAnalysis::Info.
It was mostly redundant when logged, but still can be useful to
inspect at runtime.  In the future, a better field for logging
will be available which will be similar to the "service" field
for connection records (there's not any file-format-specific
analyzers that would currently make use of such a thing).

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.

  fix bug in input-manager regarding enums that a writer reads without 0-terminating the string
  actually make sqlite work again (tests passed because the writer was not actually defined because of the define.)
  add sqlite distribution.
  fix warnings, update baselines, handle rotation
  add sqlite tests and fix small vector/set escaping bugs
  fix small bug with vectors and sets.
  make work with newer AsciiFormatter.
  start adding a different text for empty records for the sqlite writer.
  no, you will never guess from where I copied this file...

  make sqlite-writer more stable.
  make it compile with new version of AsciiInputOutput
  and adapt to AsciiInputOutput - seems to work...
