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 } ``` X-Gentoo-Bug: 601540 X-Gentoo-Bug-URL: https://bugs.gentoo.org/601540 Signed-off-by: Robin H.
