Log Message:
PR/42549: Izumi Tsutsui: parsedate does not work after 2038.
Fix multiple issues:
- Remove bogus 2038 check and add overflow checks in the appropriate places.
- Correct incomplete leap year calculation that broke things after 2100.
- Check localtime return values
- Change int calculations to time_t to avoid oveflow.
- Consistently check/return -1 and remove bogus comment about not being
able to return -1.
