* lisp/obsolete/tpu-extras.el: Avoid defadvice

(tpu--respect-bottom-scroll-margin): New function, extracted from
`newline`s defadvice.
(newline, newline-and-indent, do-auto-fill): Delete defadvice.
(tpu-set-scroll-margins): Use advice-add instead of
`ad-enable-advice`+`ad-activate`.
Use an explicit arg instead of `called-interactively-p`.
