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.

d9321e2203 FileAnalysis: remove some file events.

and file_bof_buffer.

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.

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.

7e895a3a2f FileAnalysis: replace script-layer FTP file analysis.
The notable difference here is that ftp.log now logs by default
the PORT, PASV, EPRT, EPSV commands as well as a separate line for
ftp-data channels in which file extraction was requested.

This difference isn't a direct result of now doing the file extraction
through the file analysis framework, it's just because I noticed even
the old way of tracking extracted-file name didn't work right and this
was the way I came up with so that a locally extracted file can be
associated with a data channel and then that data channel associated
with a control channel.

9ee8a9f806 Testing/external scripts no longer compute MD5 checksums for SMTP
entities.

Before, whether they did depended on libmagic. To do that,
smpt/entities.bro gets a new option `never_calc_md5`.

Also restructuring the tests a bit so that load a common
testing-setup.bro scripts that can set a global configuration.

11c437faa3 Logging framework update and mass Log::ID renaming.
- Log path's are generated in the scripting land
  now.  The default Log stream ID to path string
  mapping works like this:
    - Notice::LOG -> "notice"
    - Notice::POLICY_LOG -> "notice_policy"
    - TestModule::LOG -> "test_module"

- Logging streams updated across all of the shipped
  scripts to be more user friendly.  Instead of
  the logging stream ID HTTP::HTTP, we now have
  HTTP::LOG, etc.

- The priorities on some bro_init handlers have
  been adjusted to make the process of applying
  filters or disabling streams easier for users.

adc486c673 Merge remote-tracking branch 'origin/topic/jsiwek/smtp-refactor'
- While updating, I did some further work on the branch.

- New function in the base/utils/files for extracting filenames
  from content-dispositions.

- New script for entity excerpt extraction if you aren't interested
  in full extraction.  The data goes a log field too.

- Some renaming and reorganization of types.

- Updated tests to work with new code.

* origin/topic/jsiwek/smtp-refactor:
  Make the doc.coverage test happy.
  SMTP script refactor. (addresses #509)
