Currently every driver needs to parse the connector endpoints by it self. This is the initial work to make this generic. A generic connector has common members and connector specific members. The common members are: - type - label (optional) - links - nr_of_links The specific members are stored 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.
