Refactor cgroups to allow a group per driver to be managed directly
...
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

Make cgroups a little more efficient
...
* src/cgroup.c: Detect the mount location of every controller at
time a virCgroupPtr is created. Detect current process' placement
within group to avoid assuming it is in the root. Pass controller
ID into SetValueStr/GetValueStr to enable much duplicated code to
be eliminated
