27b0b5824a 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.

0c4968ec51 Track reachability in sources module 
Add new flag to source struct to indicate when source is selectable
(packets with good headers are received) and use a reachability
register for last 8 samples instead of the reachable flag. Source
drivers now provide only reachability updates.

4e318c1abc Require valid_header before accumulating sample 
Split test7 into two and to accumulate the sample require that all tests
pass, except the one which checks packet stratum is not higher than ours.

Also, don't mark the source as unreachable when only test4c fails.

b977c95be4 Add test for ratio of increase in delay to stddev 
Require that the ratio of the increase in delay from the minimum one in
the stats data register to the standard deviation of the offsets in the
register is less than maxdelaydevratio or the difference between
measured offset and predicted offset is larger than the increase in
delay. In the allowed delay increase is included also skew and maximum
clock frequency error.

maxdelaydevratio is 10.0 by default.

7a6ee1d729 Base poll adjustment on number of sourcestats samples 
Instead of following skew changes, adjust polling interval so that the
number of measurements used in the regression algorithm remains close to
a target value. It can be configured with a new polltarget option
(6 by default).

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.
