I was worried about doing too much refactoring in this commit since I
have hopes and dreams of it being back-patched. But I'll go ahead and do
that and if any part of this can be back-patched we'll consider that
separately.

It's true that functions are more likely to be renamed, but when I
rename a function I then search for all the places where it is used so I
can update them. If the function name appears in a comment that gets
updated as well.

If you would still prefer filenames I have no strong argument against
that, just wanted to explain my logic.
