    Windows: Avoid bottleneck on VolumeLock
    
    The VolumeLock resource was obtained during each AFSParseName()
    and held across a wide range of operations including volume
    info queries, renames, and extent requests.  These operations can
    take a long time to complete and as long as the VolumeLock was
    held exclusively there could only be one operation in flight at
    a time on a given volume.  This significantly reduced the parallelism
    of operations.
    
    The VolumeLock was not required in almost all cases.  This patchset
    adjusts the use of the VolumeLock and avoids the bottleneck.
