I don't think it's a regression - the sheepdog join code always just
counted the number of nodes to see if it can start a cluster.  That
doesn't mean I agree that it's a good behaviour, but it's defintively
how things have been as far as I can look back.

Independent of fixing a nasty crash I think this patch series also is
a great cleanup as it makes sure all of recovery simply operates on
the in-memory data structures.

I plan to look into the join code a bit more soon, and hopefully
implement a better algorithm to set the cluster live than now.
