Missed to add the SD_BUS_PROPERTY for no_delay.

TCP_DEFER_ACCEPT Allow a listener to be awakened only when data
arrives on the socket. If TCP_DEFER_ACCEPT set on a server-side
listening socket, the TCP/IP stack will not to wait for the final
ACK packet and not to initiate the process until the first packet
of real data has arrived. After sending the SYN/ACK, the server will
then wait for a data packet from a client. Now, only three packets
will be sent over the network, and the connection establishment delay
will be significantly reduced.

The tcp keep alive variables now can be configured via conf
parameter. Follwing variables are now supported by this patch.
tcp_keepalive_intvl: The number of seconds between TCP keep-alive probes
tcp_keepalive_probes: The maximum number of TCP keep-alive probes to
send before giving up and killing the connection if no response is
obtained from the other end.
tcp_keepalive_time: The number of seconds a connection needs to be
idle before TCP begins sending out keep-alive probes.

Most routers will send garbage, so make this opt-in only.

For now this only exposes the domain name (DHCP Option 15), and not
the search string (DHCP Option 119), which will be implemented in
a follow-up patch.

If "machinectl poweroff" or "machinectl reboot" is used on a
systemd-nspawn container started with --keep-unit and --register, it
should *only* send the appropriate signal to the leader PID (i.e. the
container's systemd process). It shouldn't fall through to
manager_kill_unit() to also send the signal to the unit. The latter
ends up killing systemd-nspawn, which takes down the container
prematurely.

This is supposed to remove some compiler warnings:

This makes no difference if /usr was mounted in the initrd,
and brings the behaviour of legacy systems closer to those
with a propper initrd.

This reverts commit 9528592ff8d7ff361da430285deba8196e8984d5.
Apparently TFO is actually the default at least for the server side now.
Also the setsockopt doesn't actually take a bool, but a qlen integer.

This should help in debugging issues with DHCP lease renewal.

TCP Fast Open (TFO) speeds up the opening of successiveTCP)
connections between two endpoints.It works by using a TFO cookie
in the initial SYN packet to authenticate a previously connected
client. It starts sending data to the client before the receipt
of the final ACK packet of the three way handshake is received,
skipping a round trip and lowering the latency in the start of
transmission of data.

This patch adds support for TCP TCP_NODELAY socket option. This can be
configured via NoDelay conf parameter. TCP Nagle's algorithm works by
combining a number of small outgoing messages, and sending them all at
once. This controls the TCP_NODELAY socket option.

On request of Stef Walter.

This makes strappenda3 redundant, so we remove its usage and
definition. Add a few tests along the way for sanity.

This is not certain to be likely.
Lennart says: a frequent usecase is invoking some function regularly in intervals
in such a case every single iteration we'll have to rearm

Avoids triggering timers prematurely on systems with significantly inaccurate
clocks, or some embedded platforms that lack one entirely.

Don't overflow unnecessarily.

Rather than recalculating the next timeout on every loop, we only do it when something changed.

And always put operational state first, setup state second.

THis was accidentally broken, as we truned off LLMNR far to frequently,
where we only wanted to turn off LLMNr on IPV6 on kernels lacking
support for it.

Also, return on which protocol/family/interface we found something.

The link is the 'object', so make this in line with our usual naming convention.

On receiving a message, "kernel_seqnum" is set to "serial + 1". So
subtracting 1 will cause messages like "Missed 0 kernel messages",
which should be "Missed 1 kernel messages".
