Tweak IsRelevantToMe_p in B10 (more)
...
Last night we hit a rare case of failed convergence.
f was out of sync with the rest of the world.
f: upi=[b,g,f] repairing=[a,c]
The "rest of the world" used a larger chain at:
*: upi=[c,b,g,a], repairing=[f]
And f refused to join the larger chain because of the way that
IsRelevantToMe_p was being calculated before this commit.
Hrrrm, though, I'm not convinced that this particular problem
is fixed 100% by this patch. What if the chain lengths were
the same but also UPI incompatible? e.g. if I remove 'a' from
the "real world (in the partition simulator)" example above:
f: upi=[b,g,f] repairing=[c]
*: upi=[c,b,g], repairing=[f]
Hrmmmmm, I may need to reintroduce the my-recent-adopted-projection-
flapping-like-counter thingie to try to break this kind of
incompatible deadlock.

All projection store protocol operations are now using Protocol Buffers!
...
So, there's some cheating going on, because some of the parts of
the #projection_v1{} and #p_srvr{} records aren't fully specified.
Those parts are being specified as "opaque" in the field names, e.g.
optional bytes opaque_flap = 10;
optional bytes opaque_inner = 11;
required bytes opaque_dbg = 12;
required bytes opaque_dbg2 = 13;
The serialization that's being used is erlang term sexprs. That isn't
portable. So if/when we really need to deal with a non-Erlang
language, we'll have to straighten this out further.
