[Bug 207604] [NEW] pytz includes a hard coded list of time zone names

[Launchpad Bug Tracker]

The Debian/Ubuntu packages of pytz include a patch to not install pytz's
zoneinfo database and instead load data from the system zoneinfo
database.  This keeps pytz up to date when system timezone updates are
installed which is generally a good idea.

The pytz/__init__.py includes common_timezones and all_timezones lists,
which enumerate the time zones in the database pytz was released with.
If pytz is instead using the system database, these lists may not be
correct (e.g. missing newly added time zones).

all_timezones and common_timezones should be calculated at run time.
all_timezones will need to use os.walk to discover what timezones exist.
common_timezones should be loaded from zone.tab, plus a hard coded list
of extras such as UTC and US/Eastern.
