This is the initial work to make this generic. The generic connector has some common fields and some connector specific parts. The generic one includes: - type - label - remote_port (the port where the connector is connected to) - remote_id (the endpoint where the connector is connected to) The specific fields are within a union, since only one of them can be available at the time. Since this is the initial support the patch adds only the analog-connector specific ones.
