fac96b4df4 cgroups: major update to cgroups support
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.

4f19c2f512 Support cpu usage management for Linux
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}.

e641b43849 Bring Back prefix support
We now have a team member who is interested in OpenRC on prefix, so I am
bringing it back to the main tree.

cgroups.

3247184d86 Remove prefix support
I spoke with the prefix team sometime back and was told that they do not
have an interest in using OpenRC on prefix systems.

982ac38f35 cgroups: hide configure option to turn off cgroups
Turning off the default cgroups is possible, but these groups are the
recommended setup from the kernel, so turning them off is highly
discouraged.

3e2001f6a2 add rc_cgroup option to allow disabling of cgroup default setup
Currently, cgroups are still in development, so we are not setting them
up by default. However, this default will be changed in the future.

d8bbeb184f CGroups: create the openrc cgroup hierarchy
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.

372bae3213 make rc_sys system specific
This rearranges the configuration files so it is more clear that the
rc_sys setting is system specific.

c9912942f0 update documentation for rc_sys
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.

0f3d6a01c7 remove references to the migration guide
The openrc code base is not gentoo specific, so I feel that we should
not refer to the migration guide in the comments inside the configuration
files.

3fca6bd027 allow default rc_sys value to be set at build time
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.

882a4b7d69 bug 351523: fix deprecation date for rc_sys
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.

09f990a7c8 Implement explicit selection of subsystem types.
- 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.

d6da8e8c48 sysinit is now a real runlevel that handles things like udev, dmesg and
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.
