- Revert my previous two checkins, they are rather broke with ZODB 3.3

      - Applied patch for
        http://www.zope.org/Collectors/Zope/1527. The patch
        installs a windows 'control handler'. Ctrl+C/Break etc are
        delivered asynchronously (notwithstanding the GIL) to a new
        thread. This new thread triggers a shutdown, then tricks
        asyncore into breaking out of its 'select' call.

      - The ZEO server now records its PID to a file like the ZEO
        client. Defaults to /var/ZEO.pid, and its
        configurable in /etc/zeo.conf.

- Merge a fix from the five-integration branch, with a test.

      - Collector #1507: Zope now binds again to all available IP addresses if
        ip-address is unset

      - Use 'del' instead of 'list.remove()' in
        Catalog.delColumn(). There can be only one column with the
        same name, and it could potentially break catalog metadata as
        remove() may remove more than one element from the list if
        they have the same value. Also, we already have the list index
        we are interested in deleting so it doesn't make sense to look
        up the value and call 'list.remove()' on it.

   UnIndex. Exisiting ZCatalog instances must be converted manually
   by calling the "manage_convertIndexes" method through-the-web for 
   every single ZCatalog instance.

- added manage_convertIndexes()

- removed manage_convertIndex() (obsolete)

A RNFR (rename from) request was always responded
with a response 350 (succesful). We do now check if the 
source file really exists and return a 550 response in case
if it doest not.

        full URL without query string as it appears within the location bar of
        the browser. The key has been added to provide a single key that is 
        available for vhosted and non-vhosted installations.

      - Collector #1605: VHM did not quote URLs

      - webdav.Resource: during COPY, manage_afterClone was called way
        too early, thus the object wasn't bound to the database and
        couldn't find a context. Changed to behave the same way as
        CopySupport.

      - RAMCacheManager: opimized performance by using cPickle instead
        of pickle and by using the highest pickle protocol available
        instead of using ASCII pickles (patch by Dieter Maurer)

        numbers were not rendered correctly

"foo=bar; hmm; baz=gee" will give an empty value for 'hmm' instead of
silently discarding it and the rest of the string. (Thanks to 'sirilyan'
for the patch.)

bin/zopectl test now uses os.execv, instead os os.system, so that options with characters that needs shell quoting doesn't break the command.

Updated doc/UNITTEST.txt and lib/python/Testing/README.txt to reflect progress made since UNITTEST.txt was originally written.
