[Linux-cluster] cman_tool interface change

[Patrick Caulfield]

I've changed the way cman_tool starts the cluster so if you upgrade CVS you'll
need to make sure that kernel & userspace match.

What I've done is to remove all the setsockopt() calls and replaced with with
ioctls.

Sorry for the inconvenience here but those things really are /not/ socket
options and if this code got susbmitted to the kernel team like I'd get a
roasting!
