The current check only tries to detect whether /sys/fs/cgroup exists and
whether it is writable or not. But when the init system doesn't mount
cgroups then /sys/fs/cgroup will just be an empty directory. When paired
with unprivileged containers that mount sysfs this will cause misleading
errors to be printed since /sys/fs/cgroup will be owned by user
nobody:nogroup in this case. Independent of this specific problem this
check will also be misleading when the /sys/fs/cgroup exists and is in
fact writable by the init system but isn't actually a mountpoint.
Note from William. "grep -qs" doesn't need to redirect output to
/dev/null since it is completely silent.
This fixes #209.

This function should only be called once and it does not take any
arguments.

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.

This is for #94.

This is needed to allow the service script author to set a default for
rc_ulimit inside the service script.

Supervisor setups break easily when start/stop/status functions are not
default.
Applications that write multiple PIDs to a pidfile (eg HAProxy as
described in bug 601540), can also benefit from being able to call the
default start/stop/status with modified environment variables.
Expose the default start/stop/status functions as
default_start/stop/status, and use them for the defaults
start/stop/status.
Trivial usage example:
```
stop()
{
t=$(mktemp)
for pid in $(cat $pidfile) ; do
echo $pid >$t
pidfile=$t default_stop
done
rm -f $t
}
```

The supervise-daemon process is meant to be a lightweight supervisor
which can monitor and restart a daemon if it crashes.

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.

The want dependency is similar to the use dependency. If a service
script, for example called service1, adds "want service2" to its depend
function, OpenRC will attempt to start service2, if it exists on the
system, when service1 is started.
However, service1 will start regardless of the status of
service2.

This makes it possible to override settings in rc.conf by adding a
directory @SYSCONFDIR@/rc.conf.d and putting files in this directory.
The files will be processed in lexical order, and the last setting in
these files will be used.

The original way of doing this allowed users to change the supervisor in
conf.d/*. This changes this so that the supervisor setup can be done in
the service script itself.

This will make it possible to add support for supervision suites such as
runit and s6.

This adds support for running OpenRC in a container created by
the systemd-nspawn utility.
This fixes #52.
