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}.

525c731f0e tmpfilesd: parse arguments with spaces
systemd allows the final arg in tmpfiles to contain spaces.  Using the read()
call to set the variables includes all trailing components in $arg so it
doesn't get cut off.

f886372749 functions.sh: do not hard code path in e* wrapper functions
We should use the "command" shell builtin to execute a binary from
within the wrapper with the same name. Hard coding the path to the
binary makes our test suite fail.

4ff71bd741 tmpfiles.d init.d scripts
Now that the tmpfiles.d code is more tested, actually call it from
init.d. It assumes that /run is already available when it runs.

Please note it runs TWICE.
- During sysinit, ideally just after /dev/shm is created, but before
  udev has started. After udev is also acceptable, but not ideal.
- During boot, ideally just after localmount has completed.

5615fa78d6 Drop restart_pre/restart_post
By design, restart is hard coded to run stop followed by start along
with all of the pre/post functions associated with them. Restart doesn't
need its own pre/post functions since it is possible to make any
function in an init script behave differently for a restart command by
testing against the RC_CMD environment variable.

a5b4fab732 fix handling of /run for vserver
Mount can't be used in vservers, but /run is still needed. So we create
the directory and clear it out instead of mounting a tmpfs in that
situation.

82d3918d7a move rc_svcdir to /run/openrc on Linux systems
If you are not using linux, this should not affect you.

If you are using linux, from this point forward, openrc requires the
/run directory to be a mounted tmpfs. If it is, you can run
@LIBEXECDIR@/sh/migrate-to-run.sh as root to migrate your dependency
tree and state information to the new location. If it is not, you must
create the /run directory as root with permissions 755 then reboot your
system.

8c82637e76 fix references to functions.sh
There were a couple of places where we were sourcing functions.sh in
@SYSCONFDIR@/init.d. This is only a backward compatibility symlink, so
it should not be used for openrc. The correct place to source this from
is @LIBEXECDIR@/sh.

9d0dce35c3 Let runscript enter the service dir before expand globs
Enter the service directory, like gendeps.sh does, to make sure globs are
expanded in it rather than in /. That makes sure that globbing like "need *"
will end up in all files of the init.d directory.

65be94a34a sh/tmpfiles: Upstream clarifications & quoting fixes.
Upstream has clarified via IRC:
- hardcoding /usr/lib/ is an explicit choice. It should NOT consider
  $libdir at all.
- The z/Z relabel types should call restorecon, not chcon.
- Whitespace is not allowed in tmpfiles.d/*.conf path entries,
  but is allowed in globs results. Fixed quoting of path arguments for
  this.

9fa54a8e80 Runscript: allow extra_commands to be run in chroots
The commands defined in the extra_commands variable do not depend on
whether the service is stopped or started, so it is valid to run them in
chroot environments.

Also, add a note to the runscript man page about the commands in
extra_commands being able to run whether or not the service is started.

0510c473d4 CGroups: /sys/fs/cgroups should be a tmpfs
The kernel documentation states that a cgroup file system should not be
mounted here, but a tmpfs.

This also means that we should not create a group for each process, but
we should allow the user to specify which group a process should be
assigned to. The rc_cgroup variable will be used for this purpose.

For more information, see /usr/src/linux/Documentation/cgroups/cgroups.txt.
