This allows developers to have more fine grained control over socket options supported by their platforms, particularly when there is not a nice way to encapsulate differences between IPv4 and IPv6 options (as with IP_MULTICAST_IF and IPV6_MULTICAST_IF). It also begins the work of exposing socket level and option values, although keeping it for now only to a minimum necessary to assist with setting the multicast interface for datagram sockets. This CL also marks `multicastInterface` as deprecated.
