306d4fa6f9 Pluginizing the DNP3 analyzer, plus a basic script logging requests
and replies.

Almost ready, but now 1 test fails again ...

[Note I broke git history by copying over the files into a new branch.]

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.

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).

af1809aaa3 First prototype of new analyzer framework.
This is a larger internal change that moves the analyzer
infrastructure to a more flexible model where the available analyzers
don't need to be hardcoded at compile time anymore. While currently
they actually still are, this will in the future enable external
analyzer plugins. For now, it does already add the capability to
dynamically enable/disable analyzers from script-land, replacing the
old Analyzer::Available() methods.

There are three major parts going into this:

    - A new plugin infrastructure in src/plugin. This is independent
      of analyzers and will eventually support plugins for other parts
      of Bro as well (think: readers and writers). The goal is that
      plugins can be alternatively compiled in statically or loadead
      dynamically at runtime from a shared library. While the latter
      isn't there yet, there'll be almost no code change for a plugin
      to make it dynamic later (hopefully :)

    - New analyzer infrastructure in src/analyzer. I've moved a number
      of analyzer-related classes here, including Analyzer and DPM;
      the latter now renamed to Analyzer::Manager. More will move here
      later. Currently, there's only one plugin here, which provides
      *all* existing analyzers. We can modularize this further in the
      future (or not).

    - A new script interface in base/framework/analyzer. I think that
      this will eventually replace the dpm framework, but for now
      that's still there as well, though some parts have moved over.

I've also remove the dpd_config table; ports are now configured via
the analyzer framework. For exmaple, for SSH:

    const ports = { 22/tcp } &redef;

    event bro_init() &priority=5
        {
        ...
        Analyzer::register_for_ports(Analyzer::ANALYZER_SSH, ports);
        }

As you can see, the old ANALYZER_SSH constants have more into an enum
in the Analyzer namespace.

This is all hardly tested right now, and not everything works yet.
There's also a lot more cleanup to do (moving more classes around;
removing no longer used functionality; documenting script and C++
interfaces; regression tests). But it seems to generally work with a
small trace at least.

The debug stream "dpm" shows more about the loaded/enabled analyzers.

A new option -N lists loaded plugins and what they provide (including
those compiled in statically; i.e., right now it outputs all the
analyzers).

This is all not cast-in-stone yet, for some things we need to see if
they make sense this way. Feedback welcome.

e020e034ae Script in base for detecting cases of checksum offloading.
- I added this to the base scripts because it's very minimal overhead
  and we get questions about this all the time.  Now that reporter
  messages are printed to the console, people will see the message
  clearly if they have bad checksums.

cbb31cedc3 Merge remote-tracking branch 'origin/topic/dina/modbus' into topic/robin/modbus-merge
* origin/topic/dina/modbus:
  put some make-up on Modbus analyser
  Modbus analyser, added support: FC=20,21
  Modbus analyzer,added support: FC=1,2,15,24
  Modbus analyzer, current support: FC=3,4,5,6,7,16,22,23

I cleaned up the code a bit, mainly layout style.

I did not include the *.bro scripts for now, but a test script
../testing/btest/scripts/base/protocols/modbus/events.bro that prints
out the value for each event.

Merged the Modbus traces from the ics repository into a single trace
as input for the test. They currently trigger 20 of the 34 events.

Addresses #870.

3919a35b9b Metrics framework update. Mostly to make metrics work on clusters.
- Metrics now work on cluster deployments with no caveats.  It should be
  completely transparent.  Intermediate updates to speed some detection
  will come later.

c4f4df6a79 Renaming the default loaded "init" scripts and added command line arg for "bare-mode"
- bro.init was renamed to base/init-bare.bro and base/all.bro
  was renamed to init-default.bro.

- To run in "bare mode" with only the init-bare.bro and no other
  scripts from base/, use either -b or --bare-mode.

- The environment variable to run in "bare mode" has been removed.
