6b9abe85a7 Add error events to input framework.
This change introduces error events for Table and Event readers. Users
can now specify an event that is called when an info, warning, or error
is emitted by their input reader. This can, e.g., be used to raise
notices in case errors occur when reading an important input stream.

Example:

event error_event(desc: Input::TableDescription, msg: string, level: Reporter::Level)
	{
	...
	}

event bro_init()
	{
	Input::add_table([$source="a", $error_ev=error_event, ...]);
	}

For the moment, this converts all errors in the Asciiformatter into
warnings (to show that they are non-fatal) - the Reader itself also has
to throw an Error to show that a fatal error occurred and processing
will be abort.

It might be nicer to change this and require readers to mark fatal
errors as such when throwing them.

5721db4be7 Lots of cleanup and improvement to DCE/RPC analyzer.
- It works with DCE/RPC over SMB1+2 now.
   - Using named pipes in 1+2 and the transaction cmd in SMB1.
 - Base scripts based on work by Josh Liburdi.
 - New dce_rpc.log.  Feedback on how to make this log more compact
   and useful would be appreciated.

Closes #997.

* topic/robin/sqlite-merge: (25 commits)
  Fix to make sqlite test consistent, and updating coverage baselines
  Avoid a CMake warning about 3rdparty looking like a number.
  Fixing linker error.
  and there is no has-reader.
  make sqlite3 executable required and add test-cases for errors
  Renaming src/external -> src/3rdparty
  fix a few small rough edges (mostly comments that do no longer apply)
  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 support more or less work for logging and input
  make sqlite-writer more stable.
  make it compile with new version of AsciiInputOutput
  and adapt to AsciiInputOutput - seems to work...

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.

26bf99c5a3 Add parsing for GTPv1 extension headers and control messages.

Added specific events for the create/update/delete PDP context
request/response messages.

9edbf3e53c Add GPRS Tunnelling Protocol (GTPv1) decapsulation.
This currently supports automatic decapsulation of GTP-U packets on
UDP port 2152.

The GTPv1 headers for such tunnels can be inspected by handling the
"gtpv1_g_pdu_packet" event, which has a parameter of type "gtpv1_hdr".

Analyzer and test cases are derived from submissions by Carsten Langer.

Addresses #690.

009efbcb27 Major revisions to Modbus analyzer support (not quite done yet).
- Renamed many data structures to align with most recent standard.

- Reworked modbus events to make them more canonically "Bro".

- Converted the Modbus analyzer to a simpler style for easier maintenance.

- Modbus coil related events still don't work (I haven't finished the
  function for converting the data structures).

- Modbus file record events remain incomplete.

6e0d15b55e basic sqlite writer seems to work.
does not support table and vector types because SQLite has no support for arrays.
also does not support rotation, etc.

Not really tested thoroughly - but starting bro with Log::default_writer=Log::WRITER_SQLITE
yields a couple of sqlite files that seem to contain sensible stuff.
