This also adds in the machinery to handle layout state and the deviceid cache. Note that GETDEVICEINFO is not called directly by the generic layer. Instead it is called by the drivers while parsing the LAYOUTGET opaque data in response to an unknown device id embedded therein. RFC 5661 only encodes device ids within the driver-specific opaque data.

Note that in order to have an active layout, we must get a successful response from the server. To avoid adding that machinery, this patch just includes a stub that fakes up a successful return. Since the layout is never referenced for io, this is not a problem.
