The LXC driver relies on use of cgroups to kill off LXC processes
in shutdown. If cgroups aren't available, we're unable to kill
off processes, so we must treat lack of cgroups as a fatal startup
error.

The code setting up LXC cgroups used an 'rc' variable both
for capturing the return value of methods it calls, and
its own return status. The result was that several failures
in setting up cgroups would actually result in success being
returned.
Use a separate 'ret' for tracking return value as per normal
code design in other parts of libvirt

This patch removes the explicit FSF address, and uses above instead

Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:
src/security/security_selinux.h
src/security/security_driver.h
src/security/security_selinux.c
src/security/security_apparmor.h
src/security/security_apparmor.c
src/security/security_driver.c
Move the cgroup setup code out of the lxc_controller.c file
and into lxc_cgroup.{c,h}. This reduces the size of the
lxc_controller.c file and paves the way to invoke cgroup
setup from lxc_driver.c instead of lxc_controller.c in the
future
