5214d42c07 ntp: count references to NTP server sockets 
Server sockets are now explicitly opened and closed for normal NTP
server, NTP broadcast and NTP peering. This will allow closing the
NTP port when not needed.

cd5105b1db ntp: use NTP instead of echo for presend 
Switch to NTP for presend as the echo service (RFC 862) is rarely
enabled. When presend is active, send an NTP client packet to the
server/peer and ignore the reply.

This also fixes presend with separate client sockets. The destination
port can't be changed on connected sockets, so the echo packet was sent
to the NTP port instead of the echo port.

f59ade7f80 ntp: remove socket reconnecting 
As new client socket is now created for each request, there is no need
to reconnect the socket. This is a partial revert of commit 43cca04c.

43cca04c33 ntp: reconnect client sockets 
With separate client sockets, allow the initial connect() to fail (e.g.
when the network is not reachable yet) and try to connect later when
sending the packet.

Also, reconnect the socket when the local address has changed.

9913851413 ntp: cook SO_TIMESTAMP timestamp 
This is a partial revert of 8aa9eb19c8.
With the new generic driver cooking is cheap and it should be slighly
more accurate than reusing offset correction from the scheduler
timestamps.

5c2bbaca3b ntp: use separate client sockets 
Use separate sockets for NTP server or peer and client packets. The port
number is configured by the acquisitionport directive. With the default
value of 0 the port is assigned randomly by the kernel. It can be equal
to the value configured by the port directive to use the server sockets
for all packets as before.

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.
