    Windows: pioctl path retrying with \\afs\all
    
    When the redirector is in use, \\AFS is identified as being an AFS path.
    With the SMB redirector, \\AFS was not considered a valid path.  In order
    to simulate the notion of \\AFS being the root volume, failover logic
    was added to the symlink and fs modules being triggered that
    would retry a request for \\afs\foo as \\afs\all\foo.
    
    The VIOC_SYMLINK and VIOC_AFS_CREATE_MT_PT pioctls are broken.  The
    'path' parameter that is passed in contains the directory entry that
    is to be created.  Since the AFS redirector maps \\afs to the root.afs
    volume the "foo" in \\afs\foo must exist in order for the
    _._AFS_IOCTL_._ special file to be opened.
    
    This patch implements an alternative to the failover.  If the opcode
    is one of the two listed above and the input path is a UNC path,
    then the path is re-written as \\AFS\all.  This is necessary because
    the repeated attempts to open a UNC path through the SMB redirector
    with different usernames can result in the smb session becoming
    disconnected.  If this is done when the SYSTEM account is in use,
    the tokens associated with the connection can be lost.
