* volume: redial a master that just dropped a registered stream after a second
A registered volume server that loses its master with no peer naming a
leader waited a full pulse before redialing. A restarted master is
usually back within a second, so its volumes stayed unregistered, and
uncached lookups kept failing, for most of a pulse.
For one pulse after a stream a leader had answered ends, redial on the
one-second cap. A master still down after that is redialed at the pulse
pace, so redials never come later than before.

* seaweed-volume: redial a master that just dropped a registered stream after a second
Mirror of the Go heartbeat change. The loop keeps when the last stream a
leader had answered ended, which also stands in for the
confirmed-leader-once flag (None until first registration), and redials
on the one-second cap for a pulse after that.

* seaweed-volume: test that a dropped registered stream records the loss
A fake master confirms the stream and then ends it. The server starts as
registered long ago, so only a recorded loss makes the redial come after
a second instead of a pulse.

* volume: record a lost stream only after its receiver has exited
doHeartbeatWithRetry can return on a send error while the receiver is
still handling the leader's first reply, so the deferred recorder could
read the registered flag too early and keep an old loss time. Cancel the
stream and wait for the receiver before reading it.

* test: require the prompt heartbeat redial to wait out its second

* seaweed-volume: fail the down master's dials at once in the redial test
Windows takes about two seconds to refuse a connection to a closed
loopback port, so the stream dial and the leader lookup each held the
prompt case past its two-second bound. A listener that closes every
connection fails both dials immediately on every platform.
