    Windows: Improvements to background fetch processing
    
    Log offset and length in cm_BkgPrefetch()
    
    Convert mxheld to rwheld in cm_BkgPrefetch() now that cm_scache_t
    objects use rwlocks.
    
    Do not clear CM_SCACHEFLAG_PREFETCHING from within the error
    returns from cm_CheckFetchRange().  Let the caller decide if
    that is appropriate.
    
    Add CM_BUF_CMBKGFETCH cm_buf_t cmFlag to make it possible to
    quickly detect if a background fetch operation has already
    been queued for a particular cm_buf_t data range.
