      Use value_serial for undo support. · 83c02447
      Vincent Pelletier authored 
      This mimics what FileStorage uses (file offsets) but in a relational manner.
This offloads decision of the ability to undo a transaction to storages,
avoiding 3 data loads for each object in the transaction at client side.
This also makes Neo refuse to undo transactions where object data would happen
to be equal between current value and undone value.
Finally, this is required to make database pack work properly (namely, it
prevents loosing objects which are orphans at pack TID, but are reachable
after it thanks to a transactional undo).

Also, extend storage's transaction manager so database adapter can fetch data
already sent by client in the same transaction, so it can undo multiple
transactions at once. Requires making object lock re-entrant (done in this
commit).

      Change INVALID_[OID|TID] value. · 987351fb
      Vincent Pelletier authored 
      OID 0 is a very valid oid. It's often used for the most important object of
the database: the root object. Using 0xffffffffffffffff leaves some space.

TID 0 is a very valid tid, for transactions back in unix year 0... or
ZODB tests. Using 0xffffffffffffffff leaves some space.

      Implement ReadBuffer to minimize incoming data copies. · 275a8ca2
      Grégory Wisniewski authored 
      ReadBuffer join received strings only when all requested data is available.
This avoid many useless data copies in case of big packets. The gain factor
is about 50x for a 25MB packet.
