Add the _PyTime_AsTimespec_clamp() function: similar to
_PyTime_AsTimespec(), but clamp to _PyTime_t min/max and don't raise
an exception.

PyThread_acquire_lock_timed() now uses _PyTime_AsTimespec_clamp() to
remove the Py_UNREACHABLE() code path.

  • Add _PyTime_AsTime_t() function.
  • Add PY_TIME_T_MIN and PY_TIME_T_MAX constants.
  • Replace _PyTime_AsTimeval_noraise() with _PyTime_AsTimeval_clamp().
  • Add pytime_divide_round_up().
  • Fix integer overflow in pytime_divide().
  • Add pytime_divmod() function.
