04d232d807 core: rework unit printing and implement 'combined' format
The code to print unit status formats had a long history, and became a
hard-to-manage mess of duplicate code parts. We would use sprintf() to
format a string, and then call sprintf() again… The code is reworked
to avoid repeated formattings and to streamline printing to the log
and the console.

The approach used in this patch is a bit more complex then in patches by Colin
Walter and Paweł Marciniak, because an allocation is only done if "combined"
format is used. In other cases we return the existing ->id or ->description
strings. The caller can also control whether a shorter or longer status string
should be used. This way the caller can use a shorter format where it makes
sense, for example in the cylon eye output, where we don't have enough
horizontal space.

Patch is based on Colin Walters' https://github.com/systemd/systemd/pull/15957,
and Paweł Marciniak's patch posted on fedora-devel.

Note: for some reason, the functions for printing of start and stop messages
were sepearated by some unrelated functions. They are moved to be consecutive,
but this makes the much more verbose than it would be otherwise. I found it
useful to view in gitk's "new" mode.

46a9ee5d9b core: support specifier expansion in DefaultEnvironment= and ManagerEnvironment=
Strictly speaking adding this is a compatibility break, given that
previously % weren't special. But I'd argue that was simply a bug, as
for the much more prominent Environment= service setting we always
resolved specifiers, and DEfaultEnvironment= is explicitly listed as
being the default for that. Hence, let's fix that.

Replaces: #16787

d55ed7de34 manager: add ManagerEnvironment configuration setting
This is useful for various variables that modify process behaviour. This makes
it easy to set it for pid1 without touching the kernel command line. Even for
the *user manager* this also can be convenient for the unprivileged user, who
cannot modify user@.service definition.

Variables that could be set like this include $SD_EVENT_PROFILE_DELAYS,
$SYSTEMD_FALLBACK_HOSTNAME, $SYSTEMD_MEMPOOL, $SYSTMED_RDRAND, etc.

f70e6fb471 manager: read ~/.config/systemd/user.conf in user mode
This changes the paths we read user manager config from in two ways:

- split-usr-root paths are dropped. The user manager is a poster boy for
  non-early-boot, so reading dropins only from /usr is appropriate.

- we look at ~/.config/systemd/user.conf. Users should be allowed to override
  their own config.

As user managers become more and more used, it becomes more important for users
to customize their own daemon. By reading from ~/.config, this is possible
without privileges.

Actually, systemd takes the minimum of

* b) the cgroups pids_max attribute for the system
* c) the kernel's configured maximum PID value
to calculate the DefaultTasksMax. Here, kernel.thread-max should also be methioned.

Rather than always enabling the shutdown WD on kexec, which might be

from the runtime and reboot ones. Advise in the documentation to
also use the runtime WD in conjunction with it.

b070c7c0e1 core: introduce NUMAPolicy and NUMAMask options
Make possible to set NUMA allocation policy for manager. Manager's
policy is by default inherited to all forked off processes. However, it
is possible to override the policy on per-service basis. Currently we
support, these policies: default, prefer, bind, interleave, local.
See man 2 set_mempolicy for details on each policy.

Overall NUMA policy actually consists of two parts. Policy itself and
bitmask representing NUMA nodes where is policy effective. Node mask can
be specified using related option, NUMAMask. Default mask can be
overwritten on per-service level.

61fbbac1d5 pid1: parse CPUAffinity= in incremental fashion
This makes the handling of this option match what we do in unit files. I think
consistency is important here. (As it happens, it is the only option in
system.conf that is "non-atomic", i.e. where there's a list of things which can
be split over multiple assignments. All other options are single-valued, so
there's no issue of how to handle multiple assignments.)

dc653bf487 service: handle abort stops with dedicated timeout
When shooting down a service with SIGABRT the user might want to have a
much longer stop timeout than on regular stops/shutdowns. Especially in
the face of short stop timeouts the time might not be sufficient to
write huge core dumps before the service is killed.

This commit adds a dedicated (Default)TimeoutAbortSec= timer that is
used when stopping a service via SIGABRT. In all other cases the
existing TimeoutStopSec= is used. The timer value is unset by default
to skip the special handling and use TimeoutStopSec= for state
'stop-watchdog' to keep the old behaviour.

If the service is in state 'stop-watchdog' and the service should be
stopped explicitly we still go to 'stop-sigterm' and re-apply the usual
TimeoutStopSec= timeout.

a88c5b8ac4 cgroup v2: DefaultCPUAccounting=yes if CPU controller isn't required
We now don't enable the CPU controller just for CPU accounting if we are
on 4.15+ and using pure unified hierarchy, as this is provided
externally to the CPU controller. This makes CPUAccounting=yes
essentially free, so enabling it by default when it's cheap seems like a
good idea.

143fadf369 core: remove JoinControllers= configuration setting
This removes the ability to configure which cgroup controllers to mount
together. Instead, we'll now hardcode that "cpu" and "cpuacct" are
mounted together as well as "net_cls" and "net_prio".

The concept of mounting controllers together has no future as it does
not exist to cgroupsv2. Moreover, the current logic is systematically
broken, as revealed by the discussions in #10507. Also, we surveyed Red
Hat customers and couldn't find a single user of the concept (which
isn't particularly surprising, as it is broken...)

This reduced the (already way too complex) cgroup handling for us, since
we now know whenever we make a change to a cgroup for one controller to
which other controllers it applies.

5ee91c0dbc man: fix wording a bit on the cgroup accountings options (#10509)
The &MEMORY_ACCOUNTING_DEFAULT; resolves to "yes" or "no" while the rest
of the paragraph talked about "on" and "off". Let's adjust this and
stick to "yes" and "no"...

Quite frankly I think it's not a particularly good idea to change the
docs based configuration changes... THis can only be incomplete, and the
wording is still very awkward since we repeat the same sentence twice.

fdbbee37d5 man: drop unused <authorgroup> tags from man sources
Docbook styles required those to be present, even though the templates that we
use did not show those names anywhere. But something changed semi-recently (I
would suspect docbook templates, but there was only a minor version bump in
recent years, and the changelog does not suggest anything related), and builds
now work without those entries. Let's drop this dead weight.

Tested with F26-F29, debian unstable.

$ perl -i -0pe 's/\s*<authorgroup>.*<.authorgroup>//gms' man/*xml

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.

0f943ae4ea man: add a new page with a general description of common syntax
We have a common parser, but for the user it might be
completely unobvious that the same general rules apply
to all those files. Let's add a page about the basic syntax
so that the more specific pages don't have to repeat those
details.

11a1589223 tree-wide: drop license boilerplate
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.

I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.

e0c46a7364 pid1: turn memory accounting on by default now
After discussions with @htejun it appears it's OK now to enable memory
accounting by default for all units without affecting system performance
too badly. facebook has made good experiences with deploying memory
accounting across their infrastructure.

This hence turns MemoryAccounting= from opt-in to opt-out, similar to
how TasksAccounting= is already handled. The other accounting options
remain off, their performance impact is too big still.
