fix bug where scm_from_utf8_stringn would not detect bad utf-8
* libguile/strings.c (scm_from_utf8_stringn): * libguile/symbols.c (utf8_string_equals_wide_string): The "bad UTF8" return from u8_mbtouc is a 0xfffd character, not a negative byte length. Fixes a bug in which invalid UTF-8 would not be caught. * libguile/bytevectors.c (scm_utf8_to_string): Use scm_from_utf8_stringn directly. Just a little cleanup. * test-suite/tests/iconv.test ("narrow non-ascii string"): Add test for parsing bad utf-8 with substitution.
