Pass in the length to pseudo checksum functions
Currently, the pseudo-header checksum calculation functions get
the transport layer length from the IP header. This requires that
the length be known at IP header construction time, which
does not allow transport layer translation functions to change
the length of the packet later. Have the transport functions
pass in the size directly.
