Lennart Poettering 7027ff61a3 nspawn: introduce the new /machine/ tree in the cgroup tree and move containers there 
Containers will now carry a label (normally derived from the root
directory name, but configurable by the user), and the container's root
cgroup is /machine/<label>. This label is called "machine name", and can
cover both containers and VMs (as soon as libvirt also makes use of
/machine/).

libsystemd-login can be used to query the machine name from a process.

This patch also includes numerous clean-ups for the cgroup code.

Lennart Poettering 574d5f2dfc util: rename write_one_line_file() to write_string_file() 
You can write much more than just one line with this call (and we
frequently do), so let's correct the naming.

Lennart Poettering b69d29ce04 systemctl: show main and control PID explicitly in cgroup-show 
In some cases the main/control PID of a service can be outside of the
services cgroups (for example, if logind readjusts the processes'
cgroup). In order to clarify this for the user show the main/control PID
in the cgroup tree nonetheless, but mark them specially.

Lennart Poettering 5430f7f2bc relicense to LGPLv2.1 (with exceptions) 
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.

Kay Sievers cc527a4734 split selinux label operations out of cgroup-util, socket-util 
This prevents linking of selinux and libdl for another 15 binaries.

Kay Sievers 49e942b2bc rename basic.la to shared.la and put selinux deps in shared-selinx.la 
Only 34 of 74 tools need libselinux linked, and libselinux is a pain
with its unconditional library constructor.
