Instead of looping and sending multiple signals to child processes in
cgroup_cleanup, we send sigterm followed by sleeping one second then
sigkill.
This brings us more in line with systemd's "control group" killmode
setting.
Also, this commit includes several shellcheck cleanups.
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.

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.

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

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.
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.
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.
sh/rc-cgroup.sh.in: new script to handle cgroup processing
sh/rc-cgroup.sh.in: do not use grep or cut (modification by William Hubbs)
sh/runscript.sh.in: use the cgroup script
