Supply the time delta values in the packet_info structure, and have
epan_dissect_run() take additional nstime_t * arguments for the absolute time
stamps of the previous captured and displayed frames (pass in NULL if it's the
first captured or dissected frame, and have the dissection process leave the
delta columns blank and leave out the delta-time values in the protocol tree
for the first frame, or set them to 0 if that looks too weird) and fill in
those fields based on that?
