bus-proxy: increase NOFILE limit
The bus-proxy manages the kdbus connections of all users on the system
(regarding the system bus), hence, it needs an elevated NOFILE.
Otherwise, a single user can trigger ENFILE by opening NOFILE connections
to the bus-proxy.
Note that the bus-proxy still does per-user accounting, indirectly via
the proxy/fake API of kdbus. Hence, the effective per-user limit is not
raised by this. However, we now prevent one user from consuming the whole
FD limit of the shared proxy.
Also note that there is no *perfect* way to set this. The proxy is a
shared object, so it needs a larger NOFILE limit than the highest limit
of all users. This limit can be changed dynamically, though. Hence, we
cannot protect against it. However, a raised NOFILE limit is a privilege,
so we just treat it as such and basically allow these privileged users to
be able to consume more resources than normal users (and, maybe, cause
some limits to be exceeded by this).
Right now, kdbus hard-codes 1024 max connections per user on each bus.
However, we *must not* rely on this. This limits could be easily dropped
entirely, as the NOFILE limit is a suitable limit on its on.

core: unified cgroup hierarchy support
This patch set adds full support the new unified cgroup hierarchy logic
of modern kernels.
A new kernel command line option "systemd.unified_cgroup_hierarchy=1" is
added. If specified the unified hierarchy is mounted to /sys/fs/cgroup
instead of a tmpfs. No further hierarchies are mounted. The kernel
command line option defaults to off. We can turn it on by default as
soon as the kernel's APIs regarding this are stabilized (but even then
downstream distros might want to turn this off, as this will break any
tools that access cgroupfs directly).
It is possibly to choose for each boot individually whether the unified
or the legacy hierarchy is used. nspawn will by default provide the
legacy hierarchy to containers if the host is using it, and the unified
otherwise. However it is possible to run containers with the unified
hierarchy on a legacy host and vice versa, by setting the
$UNIFIED_CGROUP_HIERARCHY environment variable for nspawn to 1 or 0,
respectively.
The unified hierarchy provides reliable cgroup empty notifications for
the first time, via inotify. To make use of this we maintain one
manager-wide inotify fd, and each cgroup to it.
This patch also removes cg_delete() which is unused now.
On kernel 4.2 only the "memory" controller is compatible with the
unified hierarchy, hence that's the only controller systemd exposes when
booted in unified heirarchy mode.
This introduces a new enum for enumerating supported controllers, plus a
related enum for the mask bits mapping to it. The core is changed to
make use of this everywhere.
This moves PID 1 into a new "init.scope" implicit scope unit in the root
slice. This is necessary since on the unified hierarchy cgroups may
either contain subgroups or processes but not both. PID 1 hence has to
move out of the root cgroup (strictly speaking the root cgroup is the
only one where processes and subgroups are still allowed, but in order
to support containers nicey, we move PID 1 into the new scope in all
cases.) This new unit is also used on legacy hierarchy setups. It's
actually pretty useful on all systems, as it can then be used to filter
journal messages coming from PID 1, and so on.
The root slice ("-.slice") is now implicitly created and started (and
does not require a unit file on disk anymore), since
that's where "init.scope" is located and the slice needs to be started
before the scope can.
To check whether we are in unified or legacy hierarchy mode we use
statfs() on /sys/fs/cgroup. If the .f_type field reports tmpfs we are in
legacy mode, if it reports cgroupfs we are in unified mode.
This patch set carefuly makes sure that cgls and cgtop continue to work
as desired.
When invoking nspawn as a service it will implicitly create two
subcgroups in the cgroup it is using, one to move the nspawn process
into, the other to move the actual container processes into. This is
done because of the requirement that cgroups may either contain
processes or other subgroups.

The legacy cgroup hierarchy does not support reliable empty
notifications in containers and if there are left-over subgroups in a

With this change we explicitly check for the container case, and whether
the unit is a "delegation" unit (i.e. one where programs may create
their own subgroups). If we are neither in a container, nor operating on
a delegation unit cgroup empty notifications become reliable and thus we
start waiting for the empty notifications again.

but reduces the effect around it.

login: support user-bus on dbus1
dbus-1.10 was just released, including systemd units to run
`dbus-daemon --session` as systemd user unit. This allows using a
user-bus with dbus1, just like we do per default with kdbus.
All the dbus libraries have already been fixed long ago to use the
user-bus as default. Hence, there's no need to set
DBUS_SESSION_BUS_ADDRESS= if we use the user-bus. However, gdm and
friends continue to spawn a session bus if this variable is not set
(instead of checking for the existence of the user-bus). Hence, we force
the user-bus, if it is available, in pam_systemd. Once gdm and friends
are fixed, we can continue to drop this again. However, that might take
a while.
With this in place, all that is needed to make the user-bus work is:
`systemctl --global enable dbus.socket`
If dbus.socket is not enabled, the legacy session-bus is still used.

cgtop: recursively count cgroup member tasks
When showing the number of tasks in a cgroup, recursively count tasks in
child cgroups and include them in the number. This ensures that the
number of tasks is cummulative the same way as memory, cpu and IO
resources are.
Old behaviour can be restored by passing the new --recursive=no switch.
