To make this possible, some things are added: - The capability to lock all tables on a tablet, to momenterily stop updates - Once the database is locked, we can create multiple consistent snapshot transactions that all share the same view of the data - Adds the capability to have replication move forward to a specific point in the transaction log This commit also refactors tabletserver and tx_engine, moving logic of state transitions into the tx engine.
