Richard Cochran 99d7c128a1 phc2sys: remove useless option. 
The 'rdelay' option has been obsoleted by the newer read_phc() logic.

Richard Cochran 0ff2d47d61 phc2sys: remove unused variable. 
The 'src' parameter to the do_servo() function is never used, so
remove it.

Miroslav Lichvar 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.
