Allow decoding of UTF-8 containing U+FFFD, the replacement character.

Browse source 
* libguile/strings.c (scm_from_utf8_stringn): Use 'u8_mbtoucr' and check
  for a decoding error by its 'nbytes' return value.  Previously we used
  'u8_mbtouc' and improperly assumed that a U+FFFD character indicated a
  decoding error.
* libguile/symbols.c (utf8_string_equals_wide_string): Likewise.
* test-suite/tests/bytevectors.test (exception:decoding-error): New
  variable.
  ("2.9 Operations on Strings"): Add tests.
