Improve handling of VOIP VLAN queries and replies.

For queries, there appear to be two different versions, one with a
2-byte value of some unknown type and one with a 1-byte value that
appears to be an "appliance type" code followed by a 2-byte VLAN ID.

For replies, there only appears to be a version with a 1-byte "appliance
type" followed by a 2-byte VLAN ID, but handle a too-short payload.

Also point to http://www.rhyshaden.com/cdp.htm in some comments.
