  log entries, duplicate detection and mapping from merkle tree leaf
  hash to entry (see doc/db.md).

  message signatures. A URL-based authorization scheme is read from
  node config.

  sometimes change after a crash. Found by Tom Fitzhenry.
- Handle unknown hashes in inclusion().

  x509 cert chains without the leaf cert.
