  src/lxc_container.h, src/lxc_controller.c, src/lxc_driver.c,
  src/lxc_driver.h, src/veth.c, src/veth.h: Move to src/lxc/
* src/opennebula/one_driver.c: Remove bogus veth.h include
* src/Makefile.am: Adjust for lxc paths
* daemon/qemud.c: Adjust include for lxc

* src/lxc_controller.c (main): Unlink sockpath only if it's non-NULL.

* src/lxc_controller.c: Don't throw error in LXC startup if
  the cgroups driver mount isn't available. Improve error
  logging for resource setup

Allow the driver level cgroup to be managed explicitly by the
hypervisor drivers, in order to detect whether to enable or
disable cgroup support for domains. Provides better error
reporting of failures. Also allow for creation of cgroups for
unprivileged drivers if controller is accessible by the user.

* src/cgroup.c, src/cgroup.h: Add an API to obtain a driver cgroup
* src/lxc_conf.h, src/lxc_controller.c, src/lxc_driver.c:
  Obtain a driver cgroup at startup and use that instead of
  re-creating everytime.
* src/util.c, src/util.h, src/libvirt_private.syms: Add a
  virGetUserName() helper

* Makefile.cfg (local-checks-to-skip): Remove sc_redundant_const.
* src/lxc_controller.c: Remove redundant "const"(s).
* src/storage_backend_fs.c: Likewise.
* src/util.h: Likewise.

* tests/qparamtest.c: Likewise.
