Sync our copy of the timezone library with IANA release tzcode2017c.

Browse Source 
This is a trivial update containing only cosmetic changes.  The point
is just to get back to being synced with an official release of tzcode,
rather than some ad-hoc point in their commit history, which is where
commit 47f849a3c left it.

There are many cosmetic (and not so cosmetic) differences from the
original tzcode library, but diffs in the upstream version should usually
be propagated to our version. Here are some notes about that.
