o Minor bugfixes:
- Set the correct day of year value when the system's localtime(_r)
or gmtime(_r) functions fail to set struct tm.
Fixes bug 13476.
- Avoid unlikely signed integer overflow in tor_timegm on systems with
32-bit time_t.
Fixes bug 13476.
o Minor enhancements (validation):
- Check all date/time values passed to tor_timegm and parse_rfc1123_time
for validity, taking leap years into account.
Improves HTTP header validation.
