commit e0c9ed44f90940b24f1c18d70452ea0ee65960be
Author: Miroslav Lichvar <mlichvar@redhat.com>
Date: Fri Aug 12 14:49:23 2011 +0200
Limit skew used in NTP test4
With iburst and very jittery sources the source skew can reach very high
values which makes the NTP test4 fail even with relatively small delays.
Limit the skew to 2000 ppm to avoid getting state where a source is unable
to accept more than first three iburst samples.

Disable maxdelayratio test by default
Change default maxdelayratio from 16384.0 to 0.0. A value larger
than 1.0 is required to enable the test.
