    wg: Refactor socket create/bind/close operations
    
    - Add the wg_socket_open() function to do socket creation and binding
      for one AF, and then use it to simplify the wg_socket_init() function.
      Meanwhil, wg_socket_bind() thus becomes obsolete and is removed.
    - Clean up wg_socket_uninit(), wg_socket_set_cookie() and
      wg_socket_set_sockopt().
    - Add the 'so_lock' lock to protect the 'struct wg_socket' fields.
      Update wg_send() accordingly.
    - Add a comment about EADDRNOTAVAIL and single-stack support.
    
    Referred to OpenBSD.
