Since QEMU 2.4.0, vhost-net uses the cross-endian support of TAP devices to
fix vnet headers. In fact, virtio-net can do the same instead of hackily
patching headers in virtio_net_hdr_swap().
This series moves the enablement of cross-endian support from vhost-net to
virtio-net: both vhost and full emulation can now benefit from it. Of course
we keep the current hack to fall back on when the backend doesn't support
cross-endian.
