ab68a9d1d3 Set maxupdateskew to 1000 ppm by default
This will prevent from using unreliable frequency estimate on iburst
when starting without drift file.

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.

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).

15e154c09d Handle immediate step in local module instead of system driver
This fixes the problem where scheduler wasn't notified about performed
steps and it also makes the command available on all supported systems.

35e662d810 Add mlockall and SCHED_FIFO support
The attached patch adds support for mlockall() as well as the SCHED_FIFO
real-time scheduler. It should result in reduced (and more consistent)
latency. Usage is documented in all the documents.

of selectable sources agree. The actual insertion/deletion is supported
only on Linux now.

8884034104 Equivalent to V1.19.99.1
This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import.  It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997.  If that
is really required, git grafts can be used.
