Making spec_node table opaque

The attached diff makes the spec_node table implementation private
to sys/miscfs/specfs/spec_vnops.c.  To retrieve a spec_node, two new
lookup functions (by device or by mount) are implemented.  Both return
a referenced vnode, for an opened block device the opened vnode is
returned so further diagnostic checks "vp == ... sd_bdevvp" will
not fire.  Otherwise any vnode matching the criteria gets returned.

Comments or objections?
