tzdata 2022g release

[Benjamin Drung]

The 2022g release contains the following changes:

* The northern edge of Chihuahua changes to US timekeeping.
* Much of Greenland stops changing clocks after March 2023.
* Fix some pre-1996 timestamps in northern Canada.
* C89 is now deprecated; please use C99 or later.
* Portability fixes for AIX, libintl, MS-Windows, musl, z/OS
* In C code, use more C23 features if available.
* C23 timegm now supported by default
* Fixes for unlikely integer overflows

Changes to future timestamps:

In the Mexican state of Chihuahua, the border strip near the US will change to agree with nearby US locations on 2022-11-30. The strip's western part, represented by Ciudad Juárez, switches from -06 all year to -07/-06 with US DST rules, like El Paso, TX. The eastern part, represented by Ojinaga, will observe US DST next year, like Presidio, TX. (Thanks to Heitor David Pinto.) A new Zone America/Ciudad_Juarez splits from America/Ojinaga.

Much of Greenland, represented by America/Nuuk, stops observing winter time after March 2023, so its daylight saving time becomes standard time. (Thanks to Jonas Nyrup and Jürgen Appel.)

ICU change: https://unicode-org.atlassian.net/browse/ICU-22217
CLDR: https://unicode-org.atlassian.net/browse/CLDR-16181

Verification is done with 'zdump'. The first timezone that gets changed in the updated package is dumped with 'zdump -v $region/$timezone_that_changed' (this needs to be greped for in /usr/share/zoneinfo/). [For example: 'zdump -v Asia/Gaza'.] This is compared to the same output after the updated package got installed. If those are different the verification is considered done.

[ Test Case for all releases ]
1) dpkg -s tzdata | grep ^Version
2) zdump -v America/Ciudad_Juarez | grep -v NULL | tail -n 1
  -> should have output, last dates should be in 2499

[Test case for releases >= 20.04 LTS]

from datetime import datetime, timedelta
from icu import ICUtzinfo, TimeZone
tz = ICUtzinfo(TimeZone.createTimeZone("America/Ciudad_Juarez"))
assert(tz.utcoffset(datetime(2022, 12, 1)) == timedelta(hours=-7))

[Test Case for releases <= 20.04 LTS]

Additionally, an upstream update of tzdata removed the 'old' SystemV timezones, so we should ensure that they are kept in Ubuntu 20.04 LTS and earlier releases. Subsequently, these should be checked for using the following:
diff <(zdump -v America/Phoenix | cut -d' ' -f2-) <(zdump -v SystemV/MST7 | cut -d' ' -f2-)
