As you can see, packet_list_append_record() in gtk/packet_list_store.c
does a g_renew() to add each additional record (packet) to the list
store. It would probably be useful to scan through a capture file for
the number of packets and then allocate enough memory so that we don't
have to renew it every time. Of course, when doing a live capture, this
wouldn't be possible.

I'm going to see (if someone doesn't beat me to it) how custom we can
make the values that are stored. Perhaps we can store IP addresses for
example in binary and have the packet list display them in a normal
format. Or... ?
