      Merge Standby-branch to trunk (mostly). · dfdcb79b
      Jeremy Hylton authored
      The Standby-branch was branched from the StandaloneZODB-1_0-branch,
      which includes the BTrees-fsIndex code.  I didn't include that change
      in the merge, but everything else.  Terse summary follows:

      Ensure that new code produces pickles acceptable to old code. · 8e9260c5
      Jeremy Hylton authored
      Add __getstate__() and __setstate__() methods.
      
      Thanks to Chris McDonough for helping me see the problem.
      
      There are extensive comments that discuss the backwards compatibility
      issues.  Basically, we must be careful that the pickles these methods
      operate on are just like the pickles generated by the old code, or
      developers couldn't switch back and forth between new and old code.
      That's a incompatibility we aren't willing to live with for now --
      perhaps not ever.
      
          # If the internal representation of PersistentMapping changes,
          # it causes compatibility problems for pickles generated by
          # different versions of the code.  Compatibility works in both
          # directions, because an application may want to share a database
          # between applications using different versions of the code.
      
          # Effectively, the original rep is part of the "API."  To provide
          # full compatibility, the getstate and setstate must read and
          # right objects using the old rep.
      
          # As a result, the PersistentMapping must save and restore the
          # actual internal dictionary using the name _container.
