This patch allows the ModbusTCP dissector (packet-mbtcp.c) to decode ModbusUDP
packets. Essentially this is the same packets over UDP instead of TCP. 

ModbusUDP isn't an offial part of the ModbusTCP specification but used by
several vendors.

The patch is rather lengthy since the original file did contain a lot of
trailing spaces and those have been removed. 

The patch have passed the fuzz testing.
