mod+kvdb+channeldb: use btcwallet new DB interface
Depends on btcsuite/btcwallet#757. Pulls in the updated version of btcwallet and walletdb that have the DB interface enhanced by their own View() and Update() methods with the reset callback/closure supported out of the box. That way the global package-level View() and Update() functions now become pure redirects.
