Merge remote-tracking branch 'origin/topic/dina/modbus' into topic/robin/modbus-merge

Browse source 
* 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.
