Change function name

Use finalize_* family names rather than dispose_* ones for socket
management so they are more descriptive than the former ones because
they announce that they not only close sockets (finalize underlaying
communciation) but also release resources allocated by them. Furthermore,
they are also used during GObject life cycle to release resources
when finalize callback takes place, so this name is more natural from the
point of view of Glib developers.
