structure to the "packet_info" structure; only stuff that's permanently
stored with each frame should be in the "frame_data" structure, and the
"column_info" structure is not guaranteed to hold the column values for
that frame at all times - it was only in the "frame_data" structure so
that it could be passed to dissectors, and, as all dissectors are now
passed a pointer to a "packet_info" structure, it could just as well be
put in the "packet_info" structure.
That saves memory, by shrinking the "frame_data" structure (there's one
of those per frame), and also lets us clean up the code a bit.

take a dissector handle as an argument, rather than a pointer to a
dissector function and a protocol ID. Associate dissector handles with
dissector table entries.

unnecessary. Clearing it before fetching anything from the packet with
a call that might throw an exception, however, is a Good Idea.
The Modbus/TCP dissector is called from a dissector table, so it doesn't
have to check if the protocol is enabled, or set "pinfo->current_proto"
- that's done for it by the dissector-table code.
