Mike Hearn f00aef2048 HDW: Add a getKeyByPath() method to wallet, and (experimental) sanity check precomputed keys before they're returned by the wallet API to guard against the potential of a bitflip in either the stored pubkey bytes, or the ECC precomputed tables. The chance of such a bit flip is small but such flips HAVE been seen in the wild against other bitcoin implementations, so it could happen to a bitcoinj user too. The consequences can be catastrophic (destroyed money) so best to try and do what we can.

HD wallets: experimental change to not trigger full lookahead when deriving keys. This allows a savvy app to get keys/addresses at startup fast, if they do so before starting up the peergroup (which wants all keys in the zone so it can calculate a Bloom filter). May be reverted if it causes trouble.
