A small handful of writers who wish to encode 64-bit values in network
order have worked around the lack of such a helper by calling the 32-bit
variant twice.
The subsequent commit will add another caller who wants to write a
64-bit value. To ease their (and the existing caller's) pain, introduce
a helper to do just that, and convert existing call-sites.
