Subject: [PATCH] Consistently use endian.h swapping API

A handful of places are still using the old "networking" API. Swap that
with the usual (no longer GNU/glibc specific) ntobe*/be*toh.

Be that to stay consistent, to improve clarity or to celebrate that the
later is part of POSIX (2024) - take your pick.
