udp: Share payload buffers between IPv4 and IPv6
Currently the IPv4 and IPv6 paths unnecessarily use different buffers for
the UDP payload. Now that we're handling the various pieces of the UDP
packets with an iov, we can split the payload part of the buffers off into
its own array shared between IPv4 and IPv6. As well as saving a little
memory, this allows the payload buffers to be neatly page aligned.
With the buffers merged, udp[46]_l2_iov_sock contain exactly the same thing
as each other and can also be merged. Likewise udp[46]_iov_splice can be
merged together.
