It's far easier to deal with GSO if we don't have to parse the packet
to figure out the header length. Add the field to the virtio_net_hdr
struct (and fix the spaces that somehow crept in there).

This implements partial checksum and GSO support for tun/tap.
We use the virtio_net_hdr: it is an ABI already and designed to
encapsulate such metadata as GSO and partial checksums.

Before: 5.06/3.39/3.82
After: 4.69/0
Implement skb_partial_csum_set, for setting partial csums on untrusted packets.
Use it in virtio_net (replacing buggy version there), it's also going
to be used by TAP for partial csum support.
