Modified Files:
        src/lib/libutil: parsedate.y

Log Message:
Check the year field of a tentative ISO-8601 date format for overflow
before committing to it being an 8601 format date, rather than after
(or the fall back grammar parser doesn't start with a clean slate).

This isn't likely to ever bother anyone, the chances of encountering
something that looks just like an 8601 format date, but with a year
field so large it overflows a long are kind of slim.   If it did happen
the chances that the string could be correctly parsed (into something
different) by the grammar are even slimmer. But better to do it properly.
