D6k: keep a take-in's new manifests unjudged on the bus until a judge pass judges them (issue 1966, ADR 0668 §4)

A judge pass that failed lost the set of manifests the take-in newly wrote, which
lived only in its memory: the next pass found no verdict, took each as accepted
before any verdict (ADR 0579 §1), and wrote a refusal as a warning. The take-in
now keeps each new digest in the indexer's own state unjudged before it writes
the module naming it; every judge pass judges those as fresh and ends a key once
its verdict is written or no module holds it. indexer_read_unjudged reads the
state; indexer_judge judges it again by hand.
