Fix initialization of frequency estimation interval.

The clock_sync_interval() function is called when logSyncInterval
changes from zero. Call it also when the clock is created to have
fest.max_count set accordingly to freq_est_interval even with zero
logSyncInterval.

Change label of frequency offset.

Change the label of the frequency offset in the clock messages printed
by ptp4l and phc2sys from "adj" to "freq" to indicate it's a frequency
value.

Also, modify clock_no_adjust() to print the frequency offset instead of
the ratio and use PRId64 instead of lld to print int64_t values.

phc2sys: Print clock reading delay.

If the delay is known, print it together with the offset and frequency.
Remove the time stamp from the output to fit it into 80 chars.
