There was a problem hiding this comment.
Last commit is overwhelming. Could prefix with wip: until dependencies are merged?

…tor impl details faa1a74 tx pool: Use class methods to hide raw map iterator impl details (MarcoFalke) Pull request description: ATMP et al would often use map iterator implementation details such as `end()` or `find()`, which is acceptable in current code. However, this not only makes it impossible to turn the maps into private members in the future but also makes it harder to replace the maps with different data structures. This is required for and split off of bitcoin#13804 Tree-SHA512: 4f9017fd1d98d9df49d25bba92655a4a97755eea161fd1cbb565ceb81bbc2b4924129d214f8a29563a77e3d8eef85a67c81245ecdc9a9e5292d419922a93cb88

This implements a layer around an immutable tx pool. The layer can be seen as a temporary throw-away shell that provides the same interface as
CTxMemPool. Its primary purpose right now is to be passed into ATMP while testing acceptance of several (potentially depending) transaction and then to be discarded.One use case could be to determine if smart contracts that are set up with multiple txs would be accepted by current consensus and policy rules.
In the future it could be extended to support recursive wrapping of layers or a way to commit changes that happened in the layer to the underlying pool or layer. Furthermore, it could be extended to be revivable after changes to the underlying layer happened. (As opposed to be single-use)
