Change extension language pretty-printers to use value API
This changes the extension language pretty-printers to use the value
API.
Note that new functions were needed, for both Guile and Python.
Currently both languages always wrap values by removing the values
from the value chain. This makes sense to avoid strange behavior with
watchpoints, and to avoid excessive memory use. However, when
printing, it's important to leave the passed-in value untouched, in
case pretty-printing does nothing -- that way the caller can still
access it.
