both sides may open sync after reset

Ready nodes will leave the first message to the pear that isn't ready.
Hello and hello reply now carry ready, so readiness is known from the
very first contact, before any sync.  Together with the sync messages
and keepalives, reports_ready is always current.

After epoch switch, pings go to everyone except ready members already
on the new epoch, these learn from the lagging peer's opening.
