a06a8b4 add InMempool() function (Jonas Schnelli)

- Make wallet descendant searching more efficient
- Add new rpc call: abandontransaction

Unconfirmed transactions that are not in your mempool either due to eviction or other means may be unlikely to be mined.  abandontransaction gives the wallet a way to no longer consider as spent the coins that are inputs to such a transaction.  All dependent transactions in the wallet will also be marked as abandoned.

- Add RPC test for abandoned and conflicted transactions.
- [Wallet] Call notification signal when a transaction is abandoned
