Merge #18982: wallet: Minimal fix to restore conflicted transaction notifications
7eaf86d3bf trivial: Suggested cleanups to surrounding code (Russell Yanofsky)
b604c5c8b5 wallet: Minimal fix to restore conflicted transaction notifications (Russell Yanofsky)

Pull request description:

  This fix is a based on the fix by Antoine Riard (ariard) in https://github.com/bitcoin/bitcoin/pull/18600.

  Unlike that PR, which implements some new behavior, this just restores previous wallet notification and status behavior for transactions removed from the mempool because they conflict with transactions in a block. The behavior was accidentally changed in two `CWallet::BlockConnected` updates: a31be09bfd and 7e89994133 from https://github.com/bitcoin/bitcoin/pull/16624, causing issue https://github.com/bitcoin/bitcoin/issues/18325.

  The change here could be improved and replaced with a more comprehensive cleanup, so it includes a detailed comment explaining future considerations.

  Fixes #18325

Internal c++ interfaces

The following interfaces are defined here:

  • Chain — used by wallet to access blockchain and mempool state. Added in #14437, #14711, #15288, and #10973.

  • ChainClient — used by node to start & stop Chain clients. Added in #14437.

  • Node — used by GUI to start & stop bitcoin node. Added in #10244.

  • Wallet — used by GUI to access wallets. Added in #10244.

  • Handler — returned by handleEvent methods on interfaces above and used to manage lifetimes of event handlers.

  • Init — used by multiprocess code to access interfaces above on startup. Added in #10102.

The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
