5d7df69116 sources: reset reachability for offline sources 
With the recent change allowing unreachable sources to remain selected,
offline sources will now be selectable only for some time, similarly to
online unreachable sources.

8f06245428 sources: allow selection of unreachable sources 
Reachability is no longer a requirement for selection. An unreachable
source can remain selected if its newest sample is not older than the
oldest sample from all reachable sources.

This is useful to prevent reselection when an accurate source uses a
very short polling interval (e.g. refclock) and is occasionally
unreachable for short periods of time.

0f8368bcf1 sources: extend source status tracking 
Add new source states and rename some states so there is one state for
each reason a source can be rejected in the source selection.

This fixes reported status when sources are selectable, but the actual
selection was postponed until next update. It will also allow more
detailed reports when the cmdmon protocol is updated.

5f68941241 sources: select only when reference can be updated 
Before selecting the new synchronization source wait until the reference
can be updated, i.e. the source has new samples.

63af4889f6 sources: drop selectable flag 
This is no longer needed with new NTP packet processing as the sources
are always selectable after first sample is accumulated.

049eae661a sources: keep synchronized status with unreachable/unselectable sources 
Following RFC 5905, don't call REF_SetUnsynchronised() when there are no
reachable or selectable sources. It's up to the client to consider the
source unsynchronized when the root distance exceeds a threshold.

The unsynchronized status is still set when no majority is reached.
