we know can't be persistent.

  prevents garbage collection.

- The FileStorage constructor now provides a boolean pack_gc option,
  which defaults to True, to control whether garbage collection is
  performed when packing by default. This can be overridden with the
  gc option to the pack method.

The ZConfig configuration for FileStorage now includes a pack-gc
  option, corresponding to the pack_gc constructor argument.

- The FileStorage constructor now has a packer keyword argument that
  allows an alternative packer to be supplied.

Added a new test class for testing packing without gc.

Moved some useful tests to PackableStorage so they are run by storages
without undo.

Moved size-limiting-cache feature to future release, since it

addresses some of the windows errors. (I think the remaining failures
here and in dbopen.txt have to do with the way time is used in
management of available connections.)

lead to breakage if an application changed directories.

blobs work for large databases on systems that don't allow many
subdirectories.
