(4.1 version, with post-review fixes) The fix for another Bug (6439) limited FROM_UNIXTIME() to TIMESTAMP_MAX_VALUE which is 2145916799 or 2037-12-01 23:59:59 GMT, however unix timestamp in general is not considered to be limited by this value. All dates up to power(2,31)-1 are valid. This patch extends allowed TIMESTAMP range so, that max TIMESTAMP value is power(2,31)-1. It also corrects FROM_UNIXTIME() and UNIX_TIMESTAMP() functions, so that max allowed UNIX_TIMESTAMP() is power(2,31)-1. FROM_UNIXTIME() is fixed accordingly to allow conversion of dates up to 2038-01-19 03:14:07 UTC. The patch also fixes CONVERT_TZ() function to allow extended range of dates. The main problem solved in the patch is possible overflows of variables, used in broken-time representation to time_t conversion (required for UNIX_TIMESTAMP).
