* library/clock.tcl: Further tweaks to the Windows time zone table

(restoring missing Mexican time zones). Added rudimentary handling of
version-2 'zoneinfo' files.   Update US DST rules so that zones
such as 'EST5EDT' get the correct transition dates.
* tests/clock.test: Added rudimentary test cases for 'zoneinfo'
parsing. Adjusted several tests that depended on obsolete
US DST transition rules.
