This reworks cgroups support so we have one variable in rc.conf for each
controller instead of each setting.
Also we add support for all of the possible cgroup controllers.
I would like to thank Alexander Vershilov for his help with testing and
reworking this code.
This commit was modified by William Hubbs as follows:
- The paths in the cgroup fs were put into variables to ease
maintenance.
- Documentation was added to rc.conf.Linux.
- The services were added originally to openrc/svcname cgroups under the
controller cgroups, but this left an "openrc" cgroup which was unused.
Now they are added to individual cgroups with the name openrc_${RC_SVCNAME}.
Currently, cgroups are still in development, so we are not setting them
up by default. However, this default will be changed in the future.

Openrc will create a cgroup hierarchy called openrc which will have all
services it starts and all subsystems attached to it. If you need other
groups/hierarchies, please use libcgroup.
This rearranges the configuration files so it is more clear that the
rc_sys setting is system specific.

Originally the plan was to deprecate this code, but this will not be
happening. There are some subsystems which can still be autodetected, so
we are keeping this code and allowing users to override the automatic
detection with this variable as well as set it to other subtypes we
cannot autodetect.

This allows the default value of rc_sys to be set when openrc is
compiled. This will allow openrc to be installed, e.g. on vserver guests
and will allow them to be rebooted without the need to edit rc.conf.
This patch is a combined effort between myself and Robin Johnson.

The deprecation notice for automatic detection of the system type stated
that the automatic detection will be removed no later than 2010/03/01,
but it should state 2011/03/01.
- Fixes bugs #347583, #349389, both of which were triggered by cgroups
being detected as the LXC subsystem type.
- Makes it much easier to select "prefix" type.
- "rc -S" will now print a warning if you have not configured rc_sys in
/etc/rc.conf
- All other semantics of rc_sys are unchanged in this patch.

mounting various bits in /dev and /sys.
init.sh JUST mounts /lib/rc/init.d (and /proc for Linux systems)
To make development of this easier we now return an empty RC_STRINGLIST
instead of a NULL for empty things.
If you don't have a udev init script installed, don't reboot your box OR
roll back to an older OpenRC version.
