c4d7e02abd Fix permission checks for cgroups
This is needed because containers may give read access to cgroups but
not allow the settings to be changed.

000503fad7 Convert OpenRC to a centralized copyright/license structure
In the past, OpenRC was a hybrid of a centralized and file-scope
license/copyright structure.

I followed the instructions from the Software Freedom Law Center [1] to
convert to a Centralized structure where possible, for easier future
maintenance.

b20a1951ad rc-cgroup.sh: Do not add leading spaces to cgroup values
We were starting the value we write to the cgroup setting file with
leading spaces and this was causing issues. This change makes sure that
we aren't adding leading spaces to the value.

993e7d7044 fix cgroup_cleanup function
The yesno test for rc_cgroup_cleanup belongs at the point where this
function is called from runscript, not in the function itself.

992807de55 Put a service on into a top hierarchy of each cgroup
This change will fix unwanted cgroup inheriting from user cgroups,
and fixes issues with systemd cgroup tracking by logind.

However this fix can lead to incorrect work for some user cgroup
controllers - so more advanced solution, that coveres such cases
will be created later.

Thanks to Fabio Erculiani (lxnay) for testing and general idea.

2391ddff77 cgroups: add support for systemd cgroup hierarchy
The systemd cgroup hierarchy support is being added so we can run
logind outside of systemd. This is needed because software that was
using consolekit is now migrating to logind.
We do not create this hierarchy, we just add services to it if it
exists.

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.
