Fix mbstring support for CP1252 encoding
It's a bit surprising how much was broken here.
- Identify filter was utterly and completely wrong.
- Instead of handling invalid CP1252 bytes as specified by
`mb_substitute_character`, it would convert them to Unicode 0xFFFD
(generic replacement character).
- When converting ISO-8859-1 to CP1252, invalid ISO-8859-1 bytes would
be passed through silently.
- Unicode codepoints from 0x80-0x9F were converted to CP1252 bytes 0x80-0x9F,
which is wrong.
- Unicode codepoint 0xFFFD was converted to CP1252 0x9F, which is very wrong.
Also clean up some unneeded code, and make the conversion table consistent with
others by using zero as a 'invalid' marker, rather than 0xFFFD.
