At this point perhaps this could be disabled in stable branches too, but
at a minimum we neither need this for the next Fedora and RHEL versions,
nor want to require Java 8 to build it.
Rebase to tzdata-2023a
- Egypt reintroduced DST, from April through October.

This makes it possible to create a RHEL-compatible source RPM
on non-RHEL distributions. The patch is still included/skipped
at build time due to the remaining conditionals.
Rebase to tzdata-2022g

change time zone to agree with nearby US locations on
2022-11-30.

America/Ojinaga.

- bug fixes for code that reads corrupted TZif data.
to keep the legacy tzdata, now build requires both jdk8 and system jdk.
I recommend to put legacy tz data to separate subpkg or to drop them at all.
Also I would recomend to rename legacy tzdat.to versioned ones (eg avazi-1.7) and to keep future, rolling tzdata unversioned, as javazi only

- Volgograd changes time zone from UTC+04 to UTC+03 on 2020-12-27.
