Matt Corallo 461e49fee2 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).
