Rein Klazes dceae02d73 - RtlTimeFieldsToTime should not normalize the time fields
structure. Instead return error when it is given an unormalized
  date.
- Use better algorithms for RtlTimeToTimeFields and
  RtlTimeFieldsToTime. RtlTimeToTimeFields is about 3 times faster.
- Add tests for RtlTimeFieldsToTime.
- SystemTimeToFileTime must fail if RtlTimeFieldsToTime fails. Users
  of SystemTimeToFileTime must do likewise.
- Remove a todo_wine from SystemTimeToFileTime tests.
- Since msvcrt.mktime must accept unnormalized dates, it cannot use
  SystemTimeToFileTime and do the calculations itself.
- Add some tests for mktime accepting unnormalized dates.
