Moved unlift to the Function companion object, ...

Moved unlift to the Function companion object, which might have been
better in the first place. Had to make a minor change to genprod, and
then I couldn't escape that unscathed. Finished the not very complete
undertaking I found there to update the scaladoc. Lots of little changes
to the generated text and code.

I changed genprod to only put a unique stamp on Function0 so we can stop
having a 100 file diff everytime an i is dotted somewhere.

Closes #3825, no review.
