udp: Factor out control structure management from udp_sock_fill_data_v[46]
The main purpose of udp_sock_fill_data_v[46]() is to construct the IP, UDP
and other headers we'll need to forward data onto the tap interface. In
addition they update the control structures (iovec and mmsghdr) we'll need
to send the messages, and in the case of pasta actually sends it.
This leads the control structure management and the send itself awkwardly
split between udp_sock_fill_data_v[46]() and their caller
udp_sock_handler(). In addition, this tail part of udp_sock_fill_datav[46]
is essentially common between the IPv4 and IPv6 versions, apart from which
control array we're working on.
Clean this up by reducing these functions to just construct the headers
and renaming them to udp_update_hdr[46]() accordingly. The control
structure updates are now all in the caller, and common for IPv4 and IPv6.
