SyncTransaction->TxAddedToMempool/BlockConnected/Disconnected
This simplifies fixing the wallet-returns-stale-info issue as we can now hold cs_wallet across an entire block instead of only per-tx (though we only actually do so in the next commit). This change also removes the NOT_IN_BLOCK constant in favor of only passing the CBlockIndex* parameter to SyncTransactions when a new block is being connected, instead of also when a block is being disconnected. This change adds a parameter to BlockConnectedDisconnected which lists the transactions which were removed from mempool due to confliction as a result of this operation. While its somewhat of a shame to make block-validation-logic generate a list of mempool changes to be included in its generated callbacks, fixing this isnt too hard. Further in this change-set, CValidationInterface starts listening to mempool directly, placing it in the middle and giving it a bit of logic to know how to route notifications from block-validation, mempool, etc (though not listening for conflicted-removals yet).
