Add a couple more of the big/little-endian conversion routines and make

them visible from userland, if need be.

I wish that the C language contained this as part of struct definintions,
but failing that, I would settle for an agreed upon set of functions for
packing/unpacking integers in various sizes from byte-streams which may
have unfriendly alignment.

This really belongs in <sys/endian.h> I guess.
