Remove the driver functions based on adjtime() and switch to the new timex driver, which is based on ntp_adjtime(). This allows chronyd to control the kernel frequency, adjust the offset with sub-microsecond accuracy, and set the kernel leap and sync status. A drawback is that the maximum slew rate is now limited by the 500 ppm maximum frequency offset, while adjtime() on NetBSD slewed by up to 5000 ppm.
