Abstract ZODB's MVCC implementation into a storage adapter.
That's applied to storages other than RelStorage.

Added a lock on the adapter
To prevent modifying the set of instances while iterating over them.

Log Message:
-----------
Fixed: tpc_vote return wasn't handled correctly.
I'd lazily assumed that undo and tpc_vote has the same sorts of
returns, but they don't. When tpc_vote isn't None (ZEO), the retrun
is a list of oid and serial pairs.

Log Message:
-----------
reverted IStorage decomposition.
It wasn't really needed or used and caused a stupid ZEO test failure.
I do think the storage API needs to be thought about and refined at
some point, but now, it's not a priority.

Log Message:
-----------
Make method copying lazy
This allows us to not worry about method overriding and avoids
creating wrapper methods (some of which were broken).
My guess is that performance is a wash. We take a tiny hit on the
first access, because ``__getattr__``, but we don't have to copy
methods we never use.

Fixed the documentation of release()
I'd started to edit it to remove implementation details and got
distracted, leaving it half edited.

Better historical connection implementation
- Lower-weight instances when not using RelStorage
- Still works with new RelStorage instances.
- Doesn't make me include loadBefore in MVCCAdapterInstance objects. :)
