* verify a tx like we verify a block (experimental) * first minimal_pool test up and running but not testing what we need to * rework tx_pool validation to use txhashset extension * minimal tx pool wired up but rough * works locally (rough statew though) delete "legacy" pool and graph code * rework the new pool into TransactionPool and Pool impls * rework pool to store pool entries with associated timer and source etc. * all_transactions * extra_txs so we can validate stempool against existing txpool * rework reconcile_block * txhashset apply_raw_tx can now rewind to a checkpoint (prev raw tx) * wip - txhashset tx tests * more flexible rewind on MMRs * add tests to cover apply_raw_txs on txhashset extension * add_to_stempool and add_to_txpool * deaggregate multi kernel tx when adding to txpoool * handle freshness in stempool handle propagation of stempool txs via dandelion monitor * patience timer and fluff if we cannot propagate to next relay * aggregate and fluff stempool is we have no relay * refactor coinbase maturity * rewrote basic tx pool tests to use a real txhashset via chain adapter * rework dandelion monitor to reflect recent discussion works locally but needs a cleanup * refactor dandelion_monitor - split out phases * more pool test coverage * remove old test code from pool (still wip) * block_building and block_reconciliation tests * tracked down chain test failure... * fix test_coinbase_maturity * dandelion_monitor now runs... * refactor dandelion config, shared across p2p and pool components * fix pool tests with new config * fix p2p tests * rework tx pool to deal with duplicate commitments (testnet2 limitation) * cleanup and address some PR feedback * add big comment about pre_tx...
