8e7f930828Add GetNewChangeDestination for getting new change Destinations (Andrew Chow)33d13edd2bReplace CReserveKey with ReserveDestinatoin (Andrew Chow)172213be5bAdd GetNewDestination to CWallet to fetch new destinations (Andrew Chow) Pull request description: The wallet should give out destinations instead of keys. It should be the one that handles the conversion from key to destination and the setting of the label, not the caller. In order to do this, two new member functions are introduced `GetNewDestination()` and `GetNewChangeDestination()`. Additionally, `CReserveKey` is changed to be `ReserveDestination` and represents destinations whose keys can be returned to the keypool. ACKs for top commit: instagibbs: re-utACK8e7f930828sipa: ACK8e7f930828. Concept ACK as this gives a much cleaner abstraction to work with, and light code review ACK. laanwj: ACK8e7f930828Tree-SHA512: 5be7051409232b71e0ef2c1fd1a3e76964ed2f5b14d47d06edc2ad3b3687abd0be2803a1adc45c0433aa2c3bed172e14f8a7e9f4a23bff70f86260b5a0497500
