* The altered Modbus checks seemed overly strict -- the pcap used
for the unit test at least had quantities/byte_count fields of
zero, to which the server responds with an error (expected).
* Most of the altered DNP3 checks seemed overly strict and caused
the unit tests to fail. The one that was just wrong was the
'start' field in header blocks.
* Removed the "start" parameter of the dnp3_header_block event
since it's always the same value.
* The SMB check failed to compile and I don't know what it intended
to do, so removed.
Includes a bit more docs/comments cleanup. We should eventually
document the events further but it should suffice for now.
* topic/robin/dnp3-merge-v3:
Tiny bit of cleanup and adapting the new test.

added condition to check DNP3 packet without app layer data
Fixing well-known port.
Pluginizing the DNP3 analyzer, plus a basic script logging requests and replies.
