2d6718bf3d units: use =yes rather than =true everywhere
So far we always used "yes" instead of "true" in all our unit files,
except for one outlier. Let's do this here too. No change in behaviour
whatsoever, except that it looks prettier ;-)

07ee5adb35 logind: change user-runtime-dir to query runtime dir size from logind via the bus
I think this is a slightly cleaner approach than parsing the
configuration file at multiple places, as this way there's only a single
reload cycle for logind.conf, and that's systemd-logind.service's
runtime.

This means that logind and dbus become a requirement of
user-runtime-dir, but given that XDG_RUNTIME_DIR is not set anyway
without logind and dbus around this isn't really any limitation.

This also simplifies linking a bit as this means user-runtime-dir
doesn't have to link against any code of logind itself.

14df094a51 units: improve Description= string a bit
Let's not use the word "wrapper", as it's not clear what that is, and in
some way any unit file is a "wrapper"... let's simply say that it's
about the runtime directory.

473b9c683a user-runtime-dir@.service: don't stop on runlevel switch (#10079)
Followup to commit 13cf422e04 ("user@.service: don't kill user manager at runlevel switch")

I think there's a general rule that units with `StopWhenUnneeded=yes` need
`IgnoreOnIsolate=yes`...  But it doesn't apply to `suspend.target` and friends.
`printer.target` and friends break on isolate even if we apply the rule[1].
That just leaves `graphical-session.target`, which is a user service.
"isolate" is *mostly* a weird attempt to emulate runlevels, so I decided
not to worry about it for user services.

1193c11a04 units: assign user-runtime-dir@.service to user-%i.slice
This service won't use much resources, but it's certainly nicer to see
it attached th the user's slice along with user@.service, so that
everything we run for a specific user is properly bound into one unit.

eb748aef4f units: order user-runtime-dir@.service after systemd-user-sessions.service
We use systemd-user-sessions.service as barrier when to allow login
sessions. With this patch user@.service is ordered after that too, so
that any login related code (which user-runtime-dir@.service is) is
guaranteed to run after the barrier, and never before.

d06e8fbce3 units: make sure user-runtime-dir@.service is Type=oneshot
We order user@.service after it, hence we need to properly know when it
finished starting up.

a9f0f5e501 logind: split %t directory creation to a helper unit
Unfortunately this needs a new binary to do the mount because there's just
too many special steps to outsource this to systemd-mount:
- EPERM needs to be treated specially
- UserRuntimeDir= setting must be obeyed
- SELinux label must be adjusted

This allows user@.service to be started independently of logind.
So 'systemctl start user@nnn' will start the user manager for user nnn.
Logind will start it too when the user logs in, and will stop it (unless
lingering is enabled) when the user logs out.

Fixes #7339.
