Do not store Merkle branches in the wallet.
Assume that when a wallet transaction has a valid block hash and transaction position in it, the transaction is actually there. We're already trusting wallet data in a much more fundamental way anyway. To prevent backward compatibility issues, a new record is used for storing the block locator in the wallet. Old wallets will see a wallet file synchronized up to the genesis block, and rescan automatically.

+Merkle branches removed from wallet
+-----------------------------------
+
+Previously, every wallet transaction stored a Merkle branch to prove its
+presence in blocks. This wasn't being used for more than an expensive
+sanity check. Since 0.12, these are no longer stored. When loading a
+0.12 wallet into an older version, it will automatically rescan to avoid
+failed checks.
