    Make undo implementation work with replication. · 7835c09e
    Vincent Pelletier authored
    The problem with previous implementation was that each storage locally
    decided what undo actually did to data. This causes problems when a
    storage doesn't have a complete view of past transaction but accepts write
    queries, ie when it replicates.
    This implementation reduces the decision to a readable subset of storage
    nodes (which are hence not replicating), and then sends that decision to
    all storage nodes, hence fixing the issue.
    Also, DatabaseManager.storeTransaction now consistently expects object's
    value_serial to be packed, not an integer.
