8d02e5f680 ntp: make use of NCR_ProcessUnknown in NCR_ProcessKnown
After recent changes the code in NCR_ProcessKnown is now identical and
can be replaced with NCR_ProcessUnknown call.

a26058d425 ntp: don't send requests with unknown key
There is no point in sending a request if the configured key is missing.
A reply would be ignored anyway.

cce7a5f15e Improve peer polling in symmetric mode
If the remote stratum is higher than ours, try to lock on the peer's
polling to minimize our response time by slightly extending our delay or
waiting for the peer to catch up with us as the random part in the
actual interval is reduced. If the remote stratum is equal to ours, try
to interleave evenly with the peer.

78ae4ebfaa Fix peer polling with shorter remote poll
If the remote peer uses a polling interval shorter than the local
minimum, the local peer will be unable to send any packets as the
timeout will be updated on every received valid packet and will never
expire.

Modify the delay calculation to aim at poll interval away since the last
transmit.

Also, share the delay calculation code with transmit_timeout().

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.

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.

(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.
