Log Message: ----------- Clean up the code for to_timestamp's conversion of year plus ISO day number to date, as per bug #4702 and subsequent discussion. In particular, make it work for years specified using AD/BC or CC fields, and fix the test for "no year specified" so that it doesn't trigger inappropriately for 1 BC (which it was doing even in code paths that had nothing to do with to_timestamp). I also did some minor code beautification in the non-ISO-day-number code path. This area has been busted all along, but because the code has been rewritten repeatedly, it would be considerable trouble to back-patch. It's such a corner case that it doesn't seem worth the effort.
