htonl and htons might be useful here: they turn native longs and short
into "network byte order". Unfortunately, this is the same as
big-endian, which is the opposite of what is required for the
6502. Still, you might implement something similar, like htoll (host to
long little-endian) and htosl (host to short little-endian).
