Make function parameters const wherever possible

The early history of this code didn't tend to make parameters const, but the
"const density" is high enough now that I often find myself wondering if
something is mutable for some reason, or just old and sloppier.  So, eliminate
this confusion by making (hopefully) all function parameters const if possible.
