Backport looks good against the 11u one and the files altered by both match the versions I generated from the tzdata bundle.

I did see a missed change in `zone.tab` but this is true of the original change in trunk, so I'll handle this under a separate bug. It may be that this file is unused and we don't need a copy of it at all.
