be4369936b Clamp tick value before calling adjtimex 
If tick is outside allowed adjtimex range, clamp it and log a warning
instead of aborting.

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).

a949ab6935 Increase burst polling interval 
To avoid getting KoD RATE from NTP server (triggering discard minimum 1)
when burst sampling, increase polling interval to 2 seconds.

e0009f9f40 Update drift file at most once per hour 
Instead of writing to the file on every reference update, update it
on first update, on exit and otherwise only once per hour.

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.

f9103531c4 Avoid large times in chronyc sources / sourcestats overflowing lines 
Main trouble was double values too large to be represented as ints being
converted to -INT_MAX and then passing the < 9999 cut.

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.

fc1514db04 Adjust refclock filter parameters 
Drop only about 40 percent of samples, change default length to 64,
require at least 4 samples between polls (or full filter for lengths
below 4).

7fb0598b50 Make linear fit in refclock dispersion calculation 
This should improve reaction to sudden temperature changes with
very precise refclocks and/or long polling intervals.
