 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.
