Since the current kernel cgroup notification logic is easily confused by
existing subgroups, let's do the same thing as in containers before. and
just not wait for non-control and non-main processes.
This should be corrected as soon as we have sane cgroup notifications
from the kernel.

- As suggested, prefix argument variables with "arg_" how we do this
usually.
- As suggested, don't involve memory allocations when storing command
line arguments.
- Break --help text at 80 chars
- man: explain that this is about SELinux
- don't do unnecessary memory allocations when putting together mount
option string

This patch adds to new options:
-Z PROCESS_LABEL
This specifies the process label to run on processes run within the container.
-L FILE_LABEL
The file label to assign to memory file systems created within the container.
For example if you wanted to wrap an container with SELinux sandbox labels, you could execute a command line the following
chcon system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -R /srv/container
systemd-nspawn -L system_u:object_r:svirt_sandbox_file_t:s0:c0,c1 -Z system_u:system_r:svirt_lxc_net_t:s0:c0,c1 -D /srv/container /bin/sh

This is now part of libsystemd.

Ensure to start getty programs on all essential system consoles on Linux on
System z. Add these essential devices to the list of virtualization_consoles
to always generate getty configurations.
For the sake of completion, the list of essential consoles is:
/dev/sclp_line0 - Operating system messages applet (LPAR)
/dev/ttysclp0 - Integrated ASCII console applet (z/VM and LPAR)
/dev/ttyS0 - Already handled by systemd (3215 console on z/VM)
/dev/hvc0 - Already handled by systemd (IUCV HVC terminal on z/VM)
Depending on the environment, z/VM or LPAR, only a subset of these terminals
are available.
See also RH BZ 860158[1] "Cannot login via Operating System Console into RHEL7
instance installed on a LPAR". This bugzilla actually blocks the installation
of Linux on System z instances in LPAR mode.

By specifiy a Controller property when creating the scope a client can
specify a bus name that will be notified with a RequestStop bus signal
when the scope has been asked to shut down, instead of sending SIGTERM
to the scope processes themselves.

The kernel will not be changed to support this, so drop the code. Listening
for all RTM_NEWLINK messages and filtering on name is reliable, so it is not
a problem.

Compute the 'secs' field as seconds since start of lease acquisition
procedure. Start off with a value of zero and increase it only for
each resent DHCP discover message. See the discussion before and
after http://www.ietf.org/mail-archive/web/dhcwg/current/msg05836.html
and Section 3.1 of RFC 2131.

Go back to Init state independent of the current state the client
is in.

A checksum field with value zero means no UDP checksum has been
computed for the packet.

In trying to track down a stupid linker bug, I noticed a bunch of
memset() calls that should be using memzero() to make it more "obvious"
that the options are correct (i.e. 0 is not the length, but the data to
set). So fix up all current calls to memset(foo, 0, length) to
memzero(foo, length).

When creating a new link, the kernel will not inform us about the new ifindex
in its ack. We have to listen for newly created devices and deduce the new
ifindex by matching on the ifname.
We used to do this by waiting for a new device from libudev, but that is asking
for trouble, as udev will happily rename the device before handing it to us.
Listen on rtnl instead, the chance of the name being changed before reaching us
is much smaller (if not nil).
Kernel patch in the works to make this unneccessary.

This was originally included in the dhcp-client at my request, but it is not
really dhcp-specific and useful outside of it, so let's pull it out.

Error out if the address family is already set to something incompatible with the
address being parsed.

These connections are never torn down, even when the DHCP specifications say that
they should be. This is useful/necessary when the rootfs (or another critical fs)
is mounted over this network connection, and dataloss would result if the connection
is lost.
This option defaults to off, but our initrd generator (TBD) will enable it when
applicable.

Given that we now have KillMode=mixed where SIGTERM might kill a smaller
set than SIGKILL we need to make sure to always go explicitly throught
the SIGKILL state to get the right end result.

process, but SIGKILL to all daemon processes
This should fix some race with terminating systemd --user, where the
system systemd instance might race against the user systemd instance
when sending SIGTERM.
