- Remove the DBTab package (moved code into Zope2.Startup.datatypes)

- Consolidate Mount.py code into MountedObject.py in ZODBMountPoint.

- Remove cant-work-now autoClassFactory.

- Removed test that was dependent on old mounting implementation.

Initial changes to support the use of multidatabases instead of Mount.py's homegrown mounting support.

Create a temporary Zope branch which will supply a working environment for ZODB blob support development.  Since we are using a branch of the ZODB HEAD to do blob development, this branch must also include ZODB database mounting support compatible with the HEAD ZODB version (we use multidatabases instead of patching Connection.py)

Prevent 'render' function in Expressions.py for being called for basic types (minor speed improvement).  See  http://www.zope.org/Collectors/Zope/1890.

        ac_aquire() ignoring the default argument

Collector #1864, #1906: fixed header normalization in appendHeader()

In the interest of keeping myself sane, I've left the "Trunk only
(unreleased)" section alone

and not just when the file is missing. This is a forward port from Zope-2_7-branch.

        problems for some .zexp files e.g. Squishdot instances)

use the pushStream/popStream model from the Zope 3 codebase instead of the
interpretWithStream model.  The two are entirely equivalent in context,
but I think the push/pop model offers more flexibility in the long run

rather then runzope to avoid all the hassle with
not detaching and thus mysteriously stopping zopes.
