4ea0f675ae units: add time-set.target
time-sync.target is supposed to indicate system clock is synchronized
with a remote clock, but as used through 241 it only provided a system
clock that was updated based on a locally-maintained timestamp.  Systems
that are powered off for extended periods would not come up with
accurate time.

Retain the existing behavior using a new time-set.target leaving
time-sync.target for cases where accuracy is required.

Closes #8861

cd9f5b68ce units: use SuccessExitStatus to ignore syntax errors in tmpfiles
This makes sense from the point of view of the whole distribution:
if there are some specific files that have syntax problems, or unknown
users or groups, or use unsupported features, failing the whole service
is not useful.

In particular, services with tmpfiles --boot should not be started after boot.
The premise of --boot is that there are actions which are only safe to do once
during boot, because the state evolves later through other means and re-running
the boot-time setup would destroy it. If services with --boot fail in the
initial transaction, they would be re-run later on when a unit which
(indirectly) depends on them is started, causing problems.

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1507501.

(If we had a mode where a service would at most run once, and would not be
started in subsequent transactions, that'd be a good additional safeguard.
Using ExecStart=-... is a bit like that, but it causes all failure to be
ignored, which is too big of a hammer.)

497d1986c1 units: order systemd-tmpfiles-clean.service after time-sync.target
That way, on systems lacking an RTC we don't false start removing aged
files too early.

db62b5b37e units: remove conditions from systemd-tmpfiles-setup
There's no point in conditionalizing systemd-tmpfiles at boot, since we
ship tmpfiles snippets ourselves, hence they will always trigger anyway.

Also, there's no reason to pull in local-fs.target from the service,
hence drop that.

49dbfa7b2b units: introduce new Documentation= field and make use of it everywhere
This should help making the boot process a bit easier to explore and
understand for the administrator. The simple idea is that "systemctl
status" now shows a link to documentation alongside the other status and
decriptionary information of a service.

This patch adds the necessary fields to all our shipped units if we have
proper documentation for them.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
