    Add rx-copy support to netfront
    
    * xen/net.c (net_data): Add rx_copy field.
    (enqueue_rx_buf): When rx_copy != 0, give grant on buffer to domD instead of
    issuing a transfer from domD.
    (hyp_net_intr): When rx_copy != 0, take back grant on buffer instead of
    finishing transfer. Do not panic on packet error, free kmsg on error.
    (hyp_net_init): Check for feature-rx-copy in backend, write 1 to
    request-rx-copy in such case. Wait for Connected state before continuing.
    Only unmap buffer when rx_copy is 0.
