Implement epan_dissect_new() and epan_dissect_free(). These are the

"top-level" dissectors that libepan-users call, instead of dissect_packet().
The epan_dissect_t holds the tvbuff after dissection so that the tvbuff's
memory is not cleared until after the proto_tree is freed. (I might stuff
the proto_tree into the epan_dissect_t, too).

What remains of dissect_packet() in packet.c handles the tvbuff initialiation.
The real meat of dissect_packet() is now in dissect_frame(), in packet-frame.c
This means that "packet.c" is no longer a dissector, os it is no longer
passed to make-reg-dotc.

Once dissect_fddi() gets two wrapper functions (dissect_fddi_swapped()
and dissect_fddi_nonswapped()), the a dissector handoff routine could
be used instead of the switch statement in dissect_frame(). I'd register
a field like "wtap.encap"
