8c8da0e0cb core: add a "Requires=" dependency between units and the slices they are located in
We place the processes we fork off in the cgroup anyway, and we probably
shouldn't be able to get that far if we couldn't set up the slice due to
resource problems or unmet conditions. Hence upgrade the dependency
between units and the slices they are located in from Wants= to
Requires=.

266f3e269d bus-util: rename bus_open_transport() to bus_connect_transport()
In sd-bus, the sd_bus_open_xyz() family of calls allocates a new bus,
while sd_bus_default_xyz() family tries to reuse the thread's default
bus. bus_open_transport() sometimes internally uses the former,
sometimes the latter family, but suggests it only calls the former via
its name. Hence, let's avoid this confusion, and generically rename the
call to bus_connect_transport().

Similar for all related calls.

And while we are at it, also change cgls + cgtop to do direct systemd
connections where possible, since all they do is talk to systemd itself.

172d7abfea systemctl: allocate arg_wall only on the heap
Previously, we'd allocate it sometimes from the heap, but otherwise let
it point directly int argv[]. Let's clean this up, so that we know
exactly how to release its resources, and do so at the end.

48ec22bc02 systemctl: remove client-side wall message support
logind sends out wall messages now, let's remove this from the systemctl
client side hence. If people build systemd without logind support they
won't get wall messages now, but that's OK.

b9e74c3994 core: rework crash handling
This introduces a new systemd.crash_reboot=1 kernel command line option
that triggers a reboot after crashing.

This also cleans up crash VT handling. Specifically, it cleans up the
configuration setting, to be between 1..63 or a boolean. This is to
replace the previous logic where "-1" meant disabled. We continue to
accept that setting, but only document the boolean syntax instead.

This also brings the documentation of the default settings in sync with
what actually happens.

The CrashChVT= configuration file setting is renamed to CrashChangeVT=,
following our usual logic of not abbreviating unnecessarily. The old
setting stays support for compat reasons.

Fixes #1300

5f5d8eab1f core: allow setting WorkingDirectory= to the special value ~
If set to ~ the working directory is set to the home directory of the
user configured in User=.

This change also exposes the existing switch for the working directory
that allowed making missing working directories non-fatal.

This also changes "machinectl shell" to make use of this to ensure that
the invoked shell is by default in the user's home directory.

Fixes #1268.

4a9b1dd4ad machine-id-commit: merge machine-id-commit functionality into machine-id-setup
And remove machine-id-commit as separate binary.

There's really no point in keeping this separate, as the sources are
pretty much identical, and have pretty identical interfaces. Let's unify
this in one binary.

Given that machine-id-commit was a private binary of systemd (shipped in
/usr/lib/) removing the tool is not an API break.

While we are at it, improve the documentation of the command substantially.

c2fc2c2560 units: increase watchdog timeout to 3min for all our services
Apparently, disk IO issues are more frequent than we hope, and 1min
waiting for disk IO happens, so let's increase the watchdog timeout a
bit, for all our services.

94f099d813 systemctl: make "systemctl is-system-running" return "offline" if we are not booted with systemd
This sounds like the better place to expose this than in "systemd-notify
--booted".

Also document the so far undocumented "unknown" state the command might
return. And rearrange the table of states documented to be more like the
one for "is-running".

Also, don't document the precise exit code of this function, just say
errors are reported != 0 or > 0...
