Do the renaming so that we don't use the special variable `v`. To
make this work also let `wtptimes3` close over the new local variable
`ratout-v` since `wtptimes3` modifies the value and is also called in
a loop, so updated values of `ratout-v` get carried to later calls.
Remove the special declarations in `wtptimes3` and `wtptimes1` too.
Remove the `declare-top` declarations for `v` too since we no longer
use the special variable `v` in this file.

We commented out `$pfet` and subroutines instead of deleting them.
There are `declare-top` statements just before and after that. Move
them inside the `progn` so that we know they're related.
Maybe we can remove this block of code at some later date.
Even though these uses of `x` aren't supposed to be special vars,
lets' rename them all anyway for consistency and also to make sure
some other file doesn't declare `x` as a special and inadvertently
make these `x`'s special.
