The timezone dumps have switched to a "slim" format since 2020b.
This has broken various packages, including
- go 1.4 (used for bootstrapping)
- haskellPackages.tz
- libical
The "fat" format can still be generated, as this commit shows.
It seems to create files that are *mostly* the slim versions with
some more data attached.
I made a mistake merge. Reverting it in c778945806 undid the state
on master, but now I realize it crippled the git merge mechanism.
As the merge contained a mix of commits from `master..staging-next`
and other commits from `staging-next..staging`, it got the
`staging-next` branch into a state that was difficult to recover.
I reconstructed the "desired" state of staging-next tree by:
- checking out the last commit of the problematic range: 4effe769e2
- `git rebase -i --preserve-merges a8a018ddc0` - dropping the mistaken
merge commit and its revert from that range (while keeping
reapplication from 4effe769e2)
- merging the last unaffected staging-next commit (803ca85c20)
- fortunately no other commits have been pushed to staging-next yet
- applying a diff on staging-next to get it into that state

Notable recent changes:
- Northern Cyprus resumed EU rules starting 2017-10-29.
- Namibia will switch from +01 with DST to +02 all year, affecting
UT offsets starting 2018-04-01.
- Sudan will switch from +03 to +02 on 2017-11-01.
- Tonga will not observe DST on 2017-11-05.
- Turks & Caicos will switch from -04 all year to -05 with US DST,
affecting UT offset starting 2018-11-04.
Hard links are not handled by nar, so installing from binary cache
unnecessarily duplicates data. Also, it's more common to use symlinks for the
tzdata package in other distributions.
We're already using tzcode inside tzdata, so let's make it available as
an output here. The reason we need it is in order to compile OpenCFLite.
