- Moved exception MountedStorageError from ZODB.POSExceptions
  to Products.TemporaryFolder.mount (now its only client).

- LP #253362:  Moved Zope2-specific module, ZODB/Mount.py, to
  Products/TemporaryFolder/mount.py (its only client is
  Products/TemporaryFolder/TemporaryFolder.py).

- Removed spurious import-time dependencies from
  Products/ZODBMountPoint/MountedObject.py.

Updated to match all new versions from the yet-unreleased Zope 3.4.1 release (`http://svn.zope.org/zope.release/branches/3.4/releases/controlled-packages.cfg?rev=99659`).

Use a layer to load the CA (we need the container handlers).

Replace messy tests with cleaned-up versions from trunk. The old tests deleted 'Zope2/version.txt' - WTFBBQ?

    
o This move breaks an import cycle in third-party code which avoids imports
  from 'Globals.'
              
o Leave the class importable from its old location without deprecation.

- The level < 0 case is basically the union of all searches for levels 0
  through to max. Just call search() for each level and use multiunion on all
  the results.
- Shorten the 'no-such-path' detection to one test.
