Subject: Use C string instead of chunk for literal text

Use zero-terminated C strings and a separate length field instead of
cmark_chunks. Literal inline text will now be copied from the parent
block's content buffer, slowing the benchmark down by 10-15%.

The node struct never references memory of other nodes now, fixing #309.
Node accessors don't have to check for delayed creation of C strings,
so parsing and iterating all literals using the public API should
actually be faster than before.
