checkNonVersionStore(): Add some default arguments to make it useful
for checkNonVersionStoreAndLoad().

__init__(), close(): Remove self._references since we sniff the pickle
instead.

_decref() -> _zaprevision(): Also, changed implementation since we
observe that it can't really be shared with the _decref() for pack,
and we're moving to a non-destructive undo instead.  So make this
function (presumably) useful for pack() and cyclic garbage
collection.  We'll see...

undo(): Mark this TBR -- to be removed -- but don't (yet) remove it.

more code sharing.

DBHOME is unused, remove.

given by tpc_begin().

_finish(), _abort(): Fix typos.

Doesn't test undo, versions, or packing.

same set of tests that Minimal also passes).  Not yet tested:
versions, undo, packing, garbage collection.

InternalInconsistencyError: the base class should be AssertionError.

Fix typo in name of table that keeps the pickle reference counts (it
should be _pickleRefcounts).

next_object() => next()

Use referencef() in a completely backwards compatible way (I happen to
have an older version of ZODB installed).

load(): Fix typo in name of table that stores the pickle data (it
should be _pickles).

store(): Use a local variable called `zero' for the 8-byte zero
pointer.  When there is no current serial number for the object
(i.e. it is being stored for the first time), initialize oserial to
zero (but not orevid).  Better printing of the ConflictError message.
When there is no version string (i.e. this is being stored in a
non-version), initialize nvrevid to zero.  Better printing of the
VersionLockError.  Fix typo in return value; we should return the
cached serial number, not the serial number that was passed in as an
argument.

FullNewInsertsTest: new class which mirrors MinimalNewInsertsTest and
performs the same set of tests on the Full database.

Also add some better docstrings.

Added __main__ section so this test can be run standalone.

MinimalBaseFramework.setUp(): Wrap the creation and opening of the
database in a try/except so that we guarantee that tearDown() is
called if there are any errors in database creation.

tearDown(): Added this to make sure that the test directories are
removed when the test is done.

FullBaseFramework: New class to mirror the same tests for the Full
database.  Based on MinimalBaseFramework.  This could use some
factorization.

DBHomeTest => MinimalDBHomeTest

FullDBHomeTest: New class to mirror the same tests for the Full
database.  Based on MinimalDBHomeTest.  This could use some
factorization.

Added __main__ section so this test can be run standalone.

Added tests which flex the complete FullLog API.
