Subject: Added cmark_ctype.h with locale-independent isspace, ispunct, etc.
Otherwise cmark's behavior varies unpredictably with the locale.
`is_punctuation` in utf8.h has also been adjusted so that everything
that counts all ASCII symbol characters count as punctuation, even
though some are not in P* character classes.
