Log:
 Improve Modbus/TCP dissector, Part 1
 
 This is a portion of the patch supplied in bug 7902 (https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=7902).  Breaking the functionality up into smaller chunks.
 
 This definitively breaks the Modbus dissection into 3 dissectors:
 Modbus - real protocol PDU
 Modbus/TCP - Encapsulation of Modbus over TCP (with a small header before PDU)
 Modbus RTU - Originally an encapsulation of Modbus over serial (with smaller header + CRC), but can also be sent over TCP.
 
 General cleanup/refactoring (including display filter names) based on the 3 dissectors.
 Also included:
 1. Enhanced dissection to include preferences for register data to be dissected as UINT16, UINT32 or FLOAT
 2. Dynamic port registration
 3. Additional fields now filterable
