Migrate init sctipt to openrc, fixes restarting problem
Dsme lifegaurd still works fine becaue the power-dsme module has a harbeat function that it registers with dsme

LGTM. @MerlijnWajer , @freemangordon ?

As discussed on IRC, NACK.

Let's dig into the dsmetool problem, and migrate away from DSME only when we have a functional system. It does a lot and I don't think we can just easily migrate half of our (core) packages.

23:08 < Wizzup> btw, I looked at dsmeutil and dsme/lifeguard.c and it looks like dsme just returns once it has sent kill()
23:08 < Wizzup> and then dsmetool also returns
23:09 < Wizzup> probably mce takes a bit too long to stop and dsmetool already returns and that's why the 'service mce restart' fails
23:09 < uvos> possibly
23:09 < Wizzup> pretty sure
23:09 < Wizzup> by default it sends SIGTERM
23:09 < uvos> ok
23:10 < uvos> yeah mce takes some time to quit
23:10 < uvos> orderly
23:10 < Wizzup> right
23:10 < uvos> mce is slow as hell in general
23:10 < uvos> i have a branch with some threads
23:10 < Wizzup> but we don't want dsme to block waiting for the process to die
23:11 < Wizzup> I mean we want dsme to take care of it proper I guess, but we also don't really want it to do that since it's not an init proc for us

Is this still a thing?

i use mce on plain debian and used to merge this in since the stock script creates a unnecessary hard dependency on dsme.
I still think dsme is just bad, and we should use systemd instead (since it provides all relevant functionality implemented much better) or use supervise-deamon at minimally reduced functionality.

Anyhow this pr is useful for anyone wanting to run mce outside maemo, so it should stick around or be made into a branch
