I was just wondering why checklicenses.py does not permit any "GPL2"
licenses, the only GPL-related ones on the list are GPL2+.

If there's a reason we require 2+ and not just 2 then we will have to
add exceptions for epan/dissectors/packet-ieee80211-radiotap-iter.[ch]
which are dual-licensed under GPL2 and BSD, but not under GPL2+.
Otherwise we can just add GPL2 to the list of valid licenses.
