I looked at using malloc()'d memory for the data sources (essentially reverting
rev 15346), but free_data_sources() is called from epan_dissect_cleanup()
(which is called from packet_list_dissect_and_cache_record()). So: we'd need
to be able to defer freeing the memory until even later. I'm not when that
"later" would have to be.
Honestly I was hoping there was a way to prevent or defer the new dissection
(that occurs during add_byte_tab()). Maybe freezing the packet list so it
doesn't move during add_byte_tab()? I don't understand the GUI stuff to hazard
more than a guess here though.
