sockets: New helper socket_address_crumple()
SocketAddress is a simple union, and simple unions are awkward: they
have their variant members wrapped in a "data" object on the wire, and
require additional indirections in C. I intend to limit its use to
existing external interfaces. New ones should use SocketAddressFlat.
I further intend to convert all internal interfaces to
SocketAddressFlat. This helper should go away then.
