-----------
Support time zone change notifications on linux
https://bugs.webkit.org/show_bug.cgi?id=314414
Reviewed by Yusuke Suzuki.
We add a timezone change observer for linux that watches both dbus
and /etc/localtime.
We add some testing helpers and some generated tests too. This uncovered
an existing bug with DST time changes.
