The differences are localized to only those files that relied on byte
handing (which are the ones you named).  It's not so much that nobyte
has advantages as that it eliminates the need for a single-octet
integer type and that is required for for all the TI 5000 DSPs.  Also,
instead of just using bigger types and masking, it implements
efficient usage of the extra width.

However, it is possible the branch is out of date; I'll have a look
this weekend.
