In regards to your comment on IRC about copying FbByteMulAdd. There was
no great reason. I was looking at doing an ARM assembler version and
wanted a more documented version of FbByteMulAdd to work with. Since I
had the a documented version I figured it would be nice to include that
in the tree. This was a low impact way to do that. However, I'm not that
attached to either way and I'll change it if you'd prefer the use
of the FbByteMulAdd macro.
