Merge #15681: [mempool] Allow one extra single-ancestor transaction per package

50cede3f5a [mempool] Allow one extra single-ancestor transaction per package (Matt Corallo)

Pull request description:

  This implements the proposed policy change from [1], which allows
  certain classes of contract protocols involving revocation
  punishments to use CPFP. Note that some such use-cases may still
  want some form of one-deep package relay, though even this alone
  may greatly simplify some lightning fee negotiation.
