    Windows: Permit cm_scache rwlock to be dropped when "Stablized"
    
    The cm_buf_opts_t cm_BufStabilize() function was implemented
    such that holding the cm_scache_t.rw lock had to be exclusively
    held until cm_BufUnstablize() was called.  Unfortunately, this
    prevents using Stabilize/Unstabilize to protect the cm_scache_t
    during Flush operations as the cm_scache_t.rw lock must be
    acquired after the cm_buf_t mutex and not before it.
    
    This patchset reimplements the synchronization logic using
    the new CM_SCACHEFLAG_SIZESETTING flag and cm_SyncOp().
