Add delayed name resolving for servers and peers
...
Resolving is retried in increasing intervals (maximum is one hour)
until it succeeds or fails with a non-temporary error.
Unresolved sources are included in the activity report as offline
sources and the online command can be used to retry it immediately.
This could be improved by resolving in a separate thread/process
to avoid blocking.

current temperature, update interval and compensation coefficients. The
clock frequency corrections are applied in local module and are invisible
in upper layers. The measurements and corrections can be logged to
tempcomp.log file.

Add fallback drifts
...
Fallback drifts are long-term averages of the system clock drift
calculated over exponentially increasing intervals. They are used when
the clock is unsynchronised to avoid quickly drifting away from true
time if there was a short-term deviation in drift before the
synchronisation was lost.
