I have reduced the requirements for the -p option to accept
any type of device. With this it should be possible to use
ptp4l to syncronize any clock device that implements the kernel
POSIX clock interface.

When synchronizing the system clock and the PTP UTC offset is valid and
traceable, set the TAI offset of the clock to have correct CLOCK_TAI
(which is implemented in the kernel as CLOCK_REALTIME + TAI offset).

Reset the STA_UNSYNC flag and maxerror value with every frequency update
to let the kernel synchronize the RTC to the system clock (11 minute mode).

The clockid parameter to the function to get the system clock's maximum
adjustment is redundant, so let us just remove it.

Update the currentUtcOffset and leap61/59 values at one minute
interval. When a leap second is detected, set the STA_INS/STA_DEL
bit for the system clock.
