man: Advertise systemd-time-wait-sync.service more (#17729)
* man: Advertise systemd-time-wait-sync.service more
The description of time-sync.target says that NTP services *should* pull
that target, but doesn't mention that e.g. systemd-timesyncd.service
doesn't actually do that. As a result, time-sync.target is reached way
earlier than people expect; see #5097, #8861, #11008.
systemd provides systemd-time-wait-sync.service to ameliorate this
problem, but doesn't feature it prominently in relevant manpages. In
fact, it's only mentioned in passing in systemd-timesyncd.service(8). As
a result, I ended up re-implementing that service, and I'm not the first
one: https://github.com/NixOS/nixpkgs/pull/51338
This patch adds a mention right in the description of time-sync.target,
which will hopefully raise awareness of this helper service.

core: order timer units after both time-sync.target and time-set.target
If users do not enable a service like systemd-time-wait-sync.target
(because they don't want to delay boot for external events, such as an
NTP sync), then timers should still take the the weaker time-set.target
feature into account, so that the clock is at least monotonic.
Hence, order timer units after both of the targets: time-sync.target
*and* time-set.target. That way, the right thing will happen regardless
if people have no NTP server (and thus also no
systemd-time-wait-sync.service or equivalent) or, only have an NTP
server (and no systemd-time-wait-sync.service), or have both.
Ordering after time-set.target is basically "free". The logic it is
backed by should be instant, without communication with the outside
going on. It's useful still so that time servers that implement the
timestamp from /var/ logic can run in later boot.

hostnamed,shared/hostname-setup: expose the origin of the current hostname
In hostnamed this is exposed as a dbus property, and in the logs in both
places.
This is of interest to network management software and such: if the fallback
hostname is used, it's not as useful as the real configured thing. Right now
various programs try to guess the source of hostname by looking at the string.
E.g. "localhost" is assumed to be not the real hostname, but "fedora" is. Any
such attempts are bound to fail, because we cannot distinguish "fedora" (a
fallback value set by a distro), from "fedora" (received from reverse dns),
from "fedora" read from /etc/hostname.
/run/systemd/fallback-hostname is written with the fallback hostname when
either pid1 or hostnamed sets the kernel hostname to the fallback value. Why
remember the fallback value and not the transient hostname in /run/hostname
instead?
We have three hostname types: "static", "transient", fallback".
– Distinguishing "static" is easy: the hostname that is set matches what
is in /etc/hostname.
– Distingiushing "transient" and "fallback" is not easy. And the
"transient" hostname may be set outside of pid1+hostnamed. In particular,
it may be set by container manager, some non-systemd tool in the initramfs,
or even by a direct call. All those mechanisms count as "transient". Trying
to get those cases to write /run/hostname is futile. It is much easier to
isolate the "fallback" case which is mostly under our control.
And since the file is only used as a flag to mark the hostname as fallback,
it can be hidden inside of our /run/systemd directory.

hostnamed: stop discriminating against "localhost" in /etc/hostname
We would sometimes ignore localhost-style names in /etc/hostname. That is
brittle. If the user configured some hostname, it's most likely because they
want to use that as the hostname. If they don't want to use such a hostname,
they should just not create the config. Everything becomes simples if we just
use the configured hostname as-is.
This behaviour seems to have been a workaround for Anaconda installer and other
tools writing out /etc/hostname with the default of "localhost.localdomain".
Anaconda PR to stop doing that: https://github.com/rhinstaller/anaconda/pull/3040.
That might have been useful as a work-around for other programs misbehaving if
/etc/hostname was not present, but nowadays it's not useful because systemd
mostly controls the hostname and it is perfectly happy without that file.
Apart from making things simpler, this allows users to set a hostname like
"localhost" and have it honoured, if such a whim strikes them.

shared/hostname-setup: leave the terminator byte alone
gethostname(3) says it's unspecified whether the string is properly terminated
when the hostname is too long. We created a buffer with one extra byte, and it
seems the intent was to let that byte serve as terminator even if we get an
unterminated string from gethostname().

Move hostname setup logic to new shared/hostname-setup.[ch]
No functional change, just moving a bunch of things around. Before
we needed a rather complicated setup to test hostname_setup(), because
the code was in src/core/. When things are moved to src/shared/
we can just test it as any function.
The test is still "unsafe" because hostname_setup() may modify the
hostname.

man/hostnamectl,hostaned,hostname1: adjust the docs to match reality
The semantics were significantly changed in
c779a44222161155c039a7fd2fd304c006590ac7
("hostnamed: Fix the way that static and transient host names interact", Feb. 2014),
but when the dbus api documentation was imported much later, it wasn't properly
adjusted to describe those new semantics.
34293dfafd2a81d80727938199769906dab321bd which added systemd.hostname= also
added new behaviour.
Let's ove various bits and pieces around so that they are in more appropriate
places. Drop recommendations to set the hostname for DHCP or mDNS purposes.
Nowadays we expect tools that want to expose some different hostname to the
outside to manage that internally without affecting visible state. Also drop
mentions of DHCP or mDNS directly setting the hostname, since nowadays network
management software is expected to (and does) go through hostnamed.
Also, add a high-level description of semantics. It glosses over the details of
handling of localhost-style names. Later commits will remove this special handling
anyway.
