Concept ACK. I think this will make writing/updating the tests less error-prone and more readable. |

Mempool improvements, branch ID awareness Whenever the local chain tip is updated, transactions in the mempool which commit to an unmineable branch ID (for example, just before a network upgrade activates, where the next block will have a different branch ID) will be removed. Includes commits cherry-picked from the following upstream PRs: - bitcoin/bitcoin#6654 - Only the mempool index change. - bitcoin/bitcoin#6776 - bitcoin/bitcoin#7020 - bitcoin/bitcoin#6915 Part of #2074.

Specifically, here we: - track mempool descendants (in-mempool transactions that depend on other mempool transactions) - turn `mapTx` into a `boost::multi_index_container` that sorts the mempool on 3 criteria: - transaction hash - fee rate - time in the mempool - Add a max size for the mempool (throwing away the cheapest txs and bumping the min relay fee, when full) - Implement on-the-fly mempool size limit with the flag `-maxmempool` - Implement `-checkmempool=N` to customize the frequency of the mempool check - Implement helper for `CTxMemPoolEntry` for the unit tests. Backports: - bitcoin#6654 - bitcoin#6722 [`*`] - bitcoin#6889 - bitcoin#6771 - bitcoin#6776 - bitcoin#6896 - bitcoin#7020 [`*`] excluding bitcoin@9e93640 as our default minimum tx fee rate of 10k satoshis is only 0,00003 USD at the time of writing.

This is only for unit tests.
This will make it easier to change the constructor to CTxMemPoolEntry in future changes, but also makes it more clear what values you are explicitly setting in the unit tests.
