d0dfa1de9e adopt struct timespec 
Replace struct timeval with struct timespec as the main data type for
timestamps. This will allow the NTP code to work with timestamps in
nanosecond resolution.

e306199588 ntp: add support for recvmmsg() 
This is used to read multiple packets with one system call. It should
work on Linux and NetBSD.

d18f9ca75a ntp: rework receiving messages 
Allocate buffers for received messages on heap instead of stack and
prepare the code for receiving multiple messages at the same time.

0a10545314 sched: rework file handling API 
Replace SCH_*InputFileHandler() functions with more general
SCH_*FileHandler(), where events are specified as a new parameter and
which will later support other file events, e.g. file ready for ouput
and exception.

The file handlers have two new parameters: file descriptor and event.

On NetBSD there is a struct in_pktinfo, but it doesn't have the
ipi_spec_dst field and it breaks compilation.

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.

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.
