similar to: [PATCH RFC v2 01/16] virtio: memory access APIs

virtio 1.0 makes all memory structures LE, so we need APIs to conditionally do a byteswap on BE architectures. To make it easier to check code statically, add virtio specific types for multi-byte integers in memory. Add low level wrappers that do a byteswap conditionally, these will be useful e.g. for vhost. Add high level wrappers that will (in the future) query device endian-ness and act

This adds wrappers to switch between native endian-ness (virtio 0.9) and virtio endian-ness (virtio 1.0). Add new typedefs as well, so that we can check statically that we didn't miss any accesses. All callers simply pass in false (0.9) so no functional change for now. Signed-off-by: Michael S. Tsirkin <mst at redhat.com> --- Sending this early so I can get feedback on this style.
