Miroslav Lichvar fefd5b4b05 Set TAI offset of system clock. 
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).

Richard Cochran 1f2c9de982 clockadj: remove useless clockid parameter. 
The clockid parameter to the function to get the system clock's maximum
adjustment is redundant, so let us just remove it.
