Rearrange struct cmark_node
Introduce multi-purpose data/len members in struct cmark_node. This is mainly used to store literal text for inlines, code and HTML blocks. Move the content strbuf for blocks from cmark_node to cmark_parser. When finalizing nodes that allow inlines (paragraphs and headings), detach the strbuf and store the block content in the node's data/len members. Free the block content after processing inlines. Reduces size of struct cmark_node by 8 bytes.
