Subject: [print] Restrict use of "debug" Termops printer.

The functions in `Termops.print_*` are meant to be debug printers,
however, they are sometimes used in non-debug code due to a API
confusion.

We thus wrap such functions into an `Internal` module, improve
documentation, and switch users to the right API.
