Notes:
    v7:
      - disable test_dgram_mcast() on windows
      - disable test_dgram_unix() on windows as it also fails
        (we test for unix support dynamically but the test is done with
         SOCK_STREAM, and it fails here with SOCK_DGRAM)
      - Tested with cirrus-ci (Thank you Thomas)
    
    v6:
      - call socket_init() otherwise socket_check_protocol_support() fails
      - if socket_check_protocol_support() fails then calls g_abort() to
        report a problem.
    
    v5:
      - disable test_stream_fd and  test_dgram_fd on windows as socketpair()
        is not defined.
      - enable test_stream_unix_abstract only on linux as "abstract"
        unix socket parameter is only defined on linux.
    
    v4:
      - rework EXPECT_STATE()
      - use g_dir_make_tmp()
    
    v3:
    - Add "-M none" to avoid error:
      "No machine specified, and there is no default"
    
    v2:
    - Fix ipv6 free port allocation
    - Check for IPv4, IPv6, AF_UNIX
    - Use g_mkdtemp() rather than g_file_open_tmp()
    - Use socketpair() in test_stream_fd()
    
    v1: compared to v14 of "qapi: net: add unix socket type support to netdev backend":
    - use IP addresses 127.0.0.1 and ::1 rather than localhost

I've also queued this since it is required for the patch:

[PATCH v4] net: stream: add a new option to automatically reconnect

Thanks
