0bb772c575 Fix delta calculation with extreme frequency offsets 
This should prevent chronyd from getting stuck and refusing new samples
due to failing test4 when the current measured frequency offset is close
to 1.0. That can happen when the system clock is stepped forward behind
chronyd's back.

df6c2a432f Fuzz transmit timestamp 
Add random bits below clock precision to the timestamp to make
it less predictable.

777303f130 Add support for different authentication hashes 
Allow different hash functions to be used in the NTP and cmdmon
protocols. This breaks the cmdmon protocol compatibility. Extended key
file format is used to specify the hash functions for chronyd and new
authhash command is added to chronyc. MD5 is the default and the only
function included in the chrony source code, other functions will be
available from libraries.

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).
