jschoubben 6f079f13a8 Checker: never lose a step's end, and ask a lost check again (issue 734's kind)
mesh-catalog #553's verdict stayed running after its step mvsgthyjed5786
passed on shanks at 19:09:31Z: the watch of that one step key, opened at
18:46:05Z, heard neither its start nor its end and never closed, so the
wait had no bound running and nothing would ever judge it.

- HeardEnds stands between the asker and each ask's watch: at every step
  end of the same build module (one watch per steps state), at a
  reconnect, the asks waited on read their keys now and are judged; a
  watch that closes is opened again, at most 3 times.
- A step the build module's next process ended (RestartReason, a delivery
  replacing it) counts as a lost ask: asked again under the claim, at most
  LostAskTries, then failed as not heard, judged again when the nodes change.
- checker_ask_again {group, why} ends a running verdict as asked again by
  hand; the checker hears its verdicts, ends the wait and claims it anew.
  Refused while a step of its pull requests runs, or for a verdict that
  is not running.
- checker_status names such checks under lost, and each step's what.

Tests: one table replaces the given-up test (rows for given up, replaced,
deaf and nudged, deaf and asked by hand); counts unchanged (147 unit, 10
integration in the checker).
