The socket_dgram method accepts a QAPI SocketAddress object which it then turns into QemuOpts before calling the inet_dgram_opts helper method. By converting the latter to use QAPI SocketAddress directly, the QemuOpts conversion step can be eliminated. This removes the very last use of QemuOpts from the sockets code, so the socket_optslist[] array is also removed. Signed-off-by: Daniel P.
