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().
