c7d0232bb1 Introduce offset correction rate
We want to correct the offset quickly, but we also want to keep the
frequency error caused by the correction itself low.

Define correction rate as the area of the region bounded by the graph of
offset corrected in time. Set the rate so that the time needed to correct
an offset equal to the current sourcestats stddev will be equal to the
update interval (assuming linear adjustment). The offset and the
time needed to make the correction are inversely proportional.

This is only a suggestion and it's up to the system driver how the
adjustment will be executed.

return EINVAL.

2a30c56f03 Quash a load of compile warnings
Kevin Lyda writes:
I enclose the following patch which removes all but three of the warnings.  i
don't have any non-linux systems handy to test a fix to the round() function.
but having it return a double should be fine.

It doesn't actually fix anything, it just shuts up -Wall, so it's certainly an
optional type of patch.

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.
