60b2c5f1fe Add README files for most Bro frameworks
The text from these README files appears on the "Bro Script Packages"
page after building the documentation.  The text for these was mostly just
copied from the existing docs.

96fe05633a Merge remote-tracking branch 'origin/topic/bernhard/input-update'
Closes #1021.

* origin/topic/bernhard/input-update:
  this event handler fails the unused-event-handlers test because it is a bit of a special case.
  ...and fix the event ordering issue. Dispatch != QueueEvent
  add Terminate to input framework to prevent potential shutdown race-conditions.
  fix warning.
  fix stderr test. ls behaves differently on errors on linux...
  small fixes.
  linux does not have strnstr
  and close only fds that are currently open (the logging framework really did not like that :) )
  A bunch of more changes for the raw reader
  make reading from stdout and stderr simultaneously work.
  allow sending data to stdin of child process
  Streaming reads from external commands work without blocking anything.
  replace popen with fork and exec.
  change raw reader to use basic c io instead of fdstream encapsulation class.

19c1816ebb Infrastructure for modularizing protocol analyzers.
There's now a new directory "src/protocols/", and the plan is for each
protocol analyzer to eventually have its own subdirectory in there
that contains everything it defines (C++/pac/bif). The infrastructure
to make that happen is in place, and two analyzers have been
converted to the new model, HTTP and SSL; there's no further
HTTP/SSL-specific code anywhere else in the core anymore (I believe :-)

Further changes:

    - -N lists available plugins, -NN lists more details on what these
      plugins provide (analyzers, bif elements). (The latter does not
      work for analyzers that haven't been converted yet).

    - *.bif.bro files now go into scripts/base/bif/; and
      scripts/base/bif/plugins/ for bif files provided by plugins.

    - I've factored out the bifcl/binpac CMake magic from
      src/CMakeLists.txt to cmake/{BifCl,Binpac}

    - There's a new cmake/BroPlugin that contains magic to allow
      plugins to have a simple CMakeLists.txt. The hope is that
      eventually the same CMakeLists.txt can be used for compiling a
      plugin either statically or dynamically.

    - bifcl has a new option -c that changes the code it generates so
      that it can be used with a plugin.

TODOs:
    - "make install" is probably broken.
    - Broxygen is probably broken for plugin-defined events.
    - event groups are broken (do we want to keep them?)

8875953751 A bunch of more changes for the raw reader
* send end_of_data event for all kind of streams
* send process_finished event containing exit code of child process for executed programs
* move raw-tests to separate directory
* expose name of input stream to readers
* better handling of some error cases in raw reader
* new force_kill option for raw reader which SIGKILLs progesses on exit

The ordering of events how they arrive in the main loop is a bit peculiar at the moment.
The process_finished event arrives in scriptland before all of the other events, even though
it should be sent last. I have not yet fully figured that out.

* origin/topic/bernhard/input-logging-commmon-functions:
  add the last of Robins suggestions (separate info-struct for constructors).
  port memory leak fix from master
  harmonize function naming
  move AsciiInputOutput over to threading
  and thinking about it, ascii-io doesn't need the separator
  change constructors
  and factor stuff out the input framework too.
  factor out ascii input/output.
  std::string accessors to escape_sequence functionality
  intermediate commit - it has been over a month since I touched this...

I cleaned up the AsciiInputOutput class somewhat, including renaming
it to AsciiFormatter, renaming some of its methods, and turning the
static methods into members for consistency.

Closes #929.

0fcc3db9a0 start adding a different text for empty records for the sqlite writer.
Sadly there also seems to be another deadlock issue which I am currently
not really able to figure out - on shutdown sometimes (too often) the main
thread + all sqlite threads wait for semaphores or mutexes.

a6d87fcab7 rename the update_finished event to end_of_data and make it fire in
more cases.

It will now not only fire after table-reads have been completed,
but also after the last event of a whole-file-read (or whole-db-read, etc.).

The interface also has been extended a bit to allow readers to
directly fire the event should they so choose. This allows the
event to be fired in direct table-setting/event-sending modes,
which was previously not possible.
