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.

table for IGMP packet types (we treat requests as "Query or Request", as
the type doesn't say which it is).
Base the query vs. request decision on the reported length of the
packet, not the captured length.
Checksum the packet only if it's not fragmented and the captured length
is greater than or equal to the amount to be checksummed, and, for
requests where we don't wire in the length to be checksummed, base it on
the reported length of the packet, not the captured length.

Use "col_add_fstr()" to set the Info column, rather than "sprintf()"ing
to a buffer and using "col_add_str()".
Add a routine that dissects unknown types of IGMP messages, and use it
for all IGMP messages for which we don't have a dissector.
