779e40ed66 ntp: delay initial transmission until first resolving ends
This will be needed to prevent loading of dump files after sources have
already accumulated samples and possibly reference was already updated
when async resolving of sources is implemented.

8671002bd7 sources: add flag that source is active
When source is set as active, it's receiving reachability updates (e.g.
offline NTP sources are not active).

Also add function to count active sources.

polling interval.

70928dba52 ntp: set maximum number of iburst samples to size of reach register
Explicitly set the number of iburst samples to the size of the register
to make sure there are at least 7 reachability updates and the
initstepslew mode can be ended.

0094128ca6 sources: split source selection from sample accumulation
This will allow postponing source selection and reference update, which
could be useful in burst modes.

cf12d72f21 ntp: use separate connected sockets for each server

socket for each server instead of using one socket per address family
for all servers.

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().
