2fcf5cbb4f Add non-PPS mode to phc2sys. 
As some PHC hardware/drivers don't provide PPS, it may be useful to keep the
system clock synchronized to PHC via clock_gettime(). While the precision
of the clock is only in microsecond range, the error seems to be quite stable.

The -d parameter now can be omitted if -s is provided.

852d587fd3 Drop the reference to best when freeing the foreign masters. 
This fixes the following issue reported by valgrind, which occurs
after a port disable/initialize subsequent to having entered slave
mode.

ba4727ccaf Throw an error if SIOCETHTOOL returns a bad PHC index. 
If the kernel supports the ioctl, but the driver does not (like igb in
kernel version 3.5), then ptp4l will incorrectly choose the system clock.
