Subject: path, tag_id3: use g_convert() instead of charConv.c

GLib provides an easier API for character set conversion than iconv().
Use g_convert() / g_convert_with_fallback() for all character
conversions.  We should optimize the path.h API later to return a
newly allocated buffer, so we can just pass GLib's return value.
