Log:
Use scm_[to/from]_utf8_string instead of scm_[to/from]_locale_string as per guile recommendation

Notes:
- in some situations the original *locale_string variant is retained. This
  is when locale encoded strings are processed (mostly file names).
- the utf8 variants don't exist for guile 1.8. For that version these
  functions will be rededefined to call the locale variants.
