    Windows: renames that overwrite existing target
    
    The Windows client up to this point has never correctly implemented
    directory renames.  For the longest time it assumed that the file
    server would not replace a pre-existing target.  As a result, when
    the target name was already in use the contents of the directory
    would end up with the target name existing but its previous file id
    associated with it.
    
    A second problem was that lookups for the source and target names
    were not performed while the directory (or directories) were exclusively
    held to ensure that competing changes could not occur.
    
    This patchset corrects both issues in cm_Rename() and adjusts the
    redirector interface to match the new behavior.
