ad7fb9434c timedated: log about unit enablement actions and enhance logs in general
The general idea is that for things which can occur repeatedly, like SetNTP
being called with the same argument, we only log at debug level. For things
which change state, like when we realize that a unit that wasn't enabled
before needs to be enabled, we log at info level.

Also, don't return success if there are no units loaded.

afaae43bb1 timedated: add back support for ntp-units.d/
We removed support for foreign services (and ntp-units.d/) in b72ddf0f4.
Support for foreign services was added back in 5d280742, but through an
environment variable.

The problem with the env var approach is that it only works as a mechanism
to select one item, and doesn't work nicely as a mechinism to create a list
of items through drop-ins (because the env var can be easily overridden, but not
extended). Having a list of "ntp providers" is important to be able to reliably disable
all of them when that is requested.

Another problem is that nobody ever bothered to care about our new "standard".
ntp-units.d/ is a nice simple format that works and is already supported by
chrony and ntpd and timedatex. If we were to introduce and ask people to follow
a new standard, there should be some good reason for this. The idea with env
vars has lower functionality, requires systemd-specific syntax. We should just
re-adopt the format that we originally introduced and that seems to work for
everyone, and more on to more interesting problems.

b910cc72c0 tree-wide: get rid of strappend()
It's a special case of strjoin(), so no need to keep both. In particular
as typing strjoin() is even shoert than strappend().

1a04395959 Enable log colors for most of tools in /usr/bin
When emitting the calendarspec warning we want to see some color.
Follow-up for 04220fda5c.

Exceptions:
- systemctl, because it has a lot hand-crafted coloring
- tmpfiles, sysusers, stdio-bridge, etc, because they are also used in
  services and I'm not sure if this wouldn't mess up something.

ca78ad1de9 headers: remove unneeded includes from util.h

84a87726ee timedate: treat 'activating' or 'inactivating' NTP client status as 'active'
When `timedatectl set-time` is called, NTP client may be in
'activating' or something. For safety, let's treat such states as
'active'.

This also changes all unit file status except for 'masked' or 'disabled'
are treated as 'enabled'.

e4de72876e util-lib: split out all temporary file related calls into tmpfiles-util.c

group things more nicely.

No code changes, just some rearranging of source files.

baaa35ad70 coccinelle: make use of SYNTHETIC_ERRNO
Ideally, coccinelle would strip unnecessary braces too. But I do not see any
option in coccinelle for this, so instead, I edited the patch text using
search&replace to remove the braces. Unfortunately this is not fully automatic,
in particular it didn't deal well with if-else-if-else blocks and ifdefs, so
there is an increased likelikehood be some bugs in such spots.

I also removed part of the patch that coccinelle generated for udev, where we
returns -1 for failure. This should be fixed independently.

37ec0fdd34 tree-wide: add clickable man page link to all --help texts
This is a bit like the info link in most of GNU's --help texts, but we
don't do info but man pages, and we make them properly clickable on
terminal supporting that, because awesome.

I think it's generally advisable to link up our (brief) --help texts and
our (more comprehensive) man pages a bit, so this should be an easy and
straight-forward way to do it.

3af0a96c0f timedate: defer the property changed signal until job of starting/stopping NTP service is finished
Before this, the property changed signal is emitted immediately after
StartUnit/StopUnit method is called. So, the running state of the NTP
client service may not updated.
This makes the timing of emitting property changed signal is deferred
until job of starting/stopping NTP client service is completed.

Fixes #9672.

2770af85ac timedate: increment reference count of sd_bus_message
The commit 5d280742b6 introduces a
barrier to suppress calling context_update_ntp_status() multiple times.
However, it just stores the address of sd_bus_message object. So,
when an address is reused on the subsequent message, then the status
of NTP clients are not updated.

This makes the stored message object is referenced by the context
object. So, the subsequent message is on cirtainly different address.

0c69794138 tree-wide: remove Lennart's copyright lines
These lines are generally out-of-date, incomplete and unnecessary. With
SPDX and git repository much more accurate and fine grained information
about licensing and authorship is available, hence let's drop the
per-file copyright notice. Of course, removing copyright lines of others
is problematic, hence this commit only removes my own lines and leaves
all others untouched. It might be nicer if sooner or later those could
go away too, making git the only and accurate source of authorship
information.

818bf54632 tree-wide: drop 'This file is part of systemd' blurb
This part of the copyright blurb stems from the GPL use recommendations:

https://www.gnu.org/licenses/gpl-howto.en.html

The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.

hence, let's just get rid of this old cruft, and shorten our codebase a
bit.
