    Windows: Adjust extent release strategy
    
    All extents were flushed whenever AFSReleaseExtentsWithFlush was
    executed.  This included a call at the completion of each
    NonCached Read operation which could result in heavy thrashing
    as the data would be released prior to it being needed by the
    application.
    
    This patchset makes the following adjustments.  First,
    AFSReleaseExtentsWithFlush() has been modified to release all
    but 1024 extents belonging to the file.  Second, NonCached Reads
    only execute AFSReleaseExtentsWithFlush() when there are more
    than 4096 extents associated with the file.  Third,
    AFSReleaseExtentsWithFlush() now has a 'bReleaseAll' parameter
    which is used for calls from AFSCleanup() and AFSFlushExtents()
    which need to be able to flush all extents attached to a FCB.
