Add "local" option to specify that the reference clock is an unsynchronized clock which is more stable than the system clock (e.g. TCXO, OCXO, or atomic clock) and it should be used as a local standard to stabilize the system clock. Handle the local refclock as a PPS refclock locked to itself which gives the unsynchronized status to be ignored in the source selection. Wait for the refclock to get at least minsamples samples and adjust the clock directly to follow changes in the refclock's sourcestats frequency and offset. There should be at most one refclock specified with this option.
