16ff3cd8df check whether /sys/fs/cgroup is a mountpoint
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.

2b0345165e Make cgroup_cleanup send only one sigterm and sigkill
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.

66ed8082d0 sh/openrc-run: source service script before ulimit is processed
This is needed to allow the service script author to set a default for
rc_ulimit inside the service script.

sh/openrc-run.sh: expose default start/stop/status
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
  }
```

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.

33d3f33b3c Implement "want" dependency
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.

c09eeca491 Add rc.conf.d support
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.
