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.

6432da6a69 basic/pager: ignore ^C when piping to less and K is not set
Normally, we want to immediately quit on ^C. But when we are running under
less, people may set SYSTEMD_LESS without K, in which case they can use ^C to
communicate with less, and e.g. start and stop following input.

Fixes #6405.

4b3ca79ea9 udevd: allow more parameters to be set through udev.conf
Rebooting to set change the kernel command line to set some udev parameters is
inconvenient. Let's allow setting more stuff in the config file.

Also drop quotes from around "info" in udev.conf. We need to accept them for
compatibility, but there is no reason to use them.

a9353a5c5b core: log about /var/run/ prefix used in PIDFile=, patch it to be /run instead
In a way this is a follow-up for
a2d1fb882c, but adds a similar warning for
PIDFile=.

There's a much stronger case for doing this kind of notification in
tmpfiles.d (since it helps relating lines to each other for the purpose
of merging them). Doing this for PIDFile= is mostly about being
systematic and copying tmpfiles.d/ behaviour here.

While we are at it, let's also support relative filenames in PIDFile=
now, and prefix them with /run, to make them absolute.

c4e48030cf sd-bus: make "close+flush-on-exit" optional when using sd-event with sd-bus
This adds a new pair of API calls sd_bus_set_close_on_exit() and
sd_bus_get_close_on_exit(). They control whether an sd_bus object
attached to a an sd-event loop shall automatically be flushed/closed
when the event loop goes down. Usually that's a good thing, except for
very few cases where the bus connection is longer living than the event
loop it is attached on. Specifically, this is the case for nspawn, where
we run the event loop only while the container is up, but afterwards
still want to be able to use the bus connection.

0ccc48b5b8 man: Fix implicit dep info for timer units (#10679)
This reorganizes the systemd.timer man page so that it doesn't claim
there are no implicit dependencies right after specifying the implicit
dependencies, and so that it matches the other man pages for units. This
fixes a mistake introduced by commit aed5cb03db.

53bd20ea06 man: don't claim that AssertXYZ= expressions failing had an effect on unit state
In the documentation for ConditionXYZ= we claimed that AssertXYZ= would
have an effect on unit state (which is wrong), while at the
documentation for AssertXYZ= we said it only has an effect on the job,
but not the unit (which is right). Let's fix this contradiction, and
only claim the latter.

Also, fix a couple of other things (for example, stop talking about a
"failure state", but let's just expressly called it "the 'failed' state",
as that's the actual name of that state.

Finally, let's emphasize again when the conditions/assertions are
executed, and that they hence are not useful to conditionalize deps.

users to quickly discover the option they need to add in order to see

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.

3f1c1287a9 analyze: Add "timespan" command to dump time span in usec
This is useful for a couple of cases, I'm mostly interested in case #1:

1. Verifying "reasonable" values in a trivially scriptable way
2. Debugging unexpected time span parsing directly

Test Plan:

```
% build/systemd-analyze timespan 20
Original: 20
      μs: 20
   Human: 20us
% build/systemd-analyze timespan 20ms
Original: 20ms
      μs: 20000
   Human: 20ms
% build/systemd-analyze timespan 20z
Failed to parse time span '20z': Invalid argument
