6b0198c2d7 Replace all CROAK calls with assert or LOG_FATAL
Remove croak() and use assert() or LOG_FATAL() everywhere. Hopefully
the problems with debugging mentioned in the croak() comment are long gone.

2a64b75893 Regenerate critical values for number of runs
Generate more values to allow regression with 128 samples. Possibly a
different approach was used to generate the values, or the previous table
was actually using 11% critical region and had an extra value in the
12th place.

100f732e20 Remove SST_DoUpdateRegression

sourcestats.

5fb0a9d53b Rehash NTP source table after removing source
This is needed to avoid breaking a probe sequence and losing another
source. It is costly, but it's not expected to happen frequently.

aa91c608f4 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.

3d260d41b3 Don't retry resolving in DNS_Name2IPAddress
Instead of retrying to resolve it in the function and blocking for a
long time, return a TryAgain status and let the caller retry it later if
necessary.

1a7415a6ab Return actual frequency in drv_set_freq functions
This is needed to keep sourcestats accurate when the actual frequency is
different from the requested frequency due to clamping (or possibly
rounding in future system drivers).

14d2576924 Remove absolute frequency from handler parameters
None of the current handlers really need it and with temperature
compensation enabled it would be necessary to undo the compensation
before passing it to the handlers.

c386d11765 Add temperature compensation
A new tempcomp directive can be used to specify a file for reading
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.

f12bc10917 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.

b9b0326d15 Reduce noise in refclock sample dispersions
Use the estimated dispersion only if it's higher than long-term average.
This should improve performance with short polling intervals.
