* fix mempool accessing, rewrite get_mempool_entries_by_addresses * fix counter, add verbose * fmt * addresses as string * Define error in case utxoEntry is missing. * fix error variable to string * stop tests from failing (see in code comment) * access both pools in the same state via parameters * get rid of todo message * fmt - very important! * perf: scriptpublickey in mempool, no txscript. * address reveiw * fmt fix * mixed up isorphan bool, pass tests now * do map preallocation in mempoolbyaddresses * no proallocation for orphanpool sending.
