Create a <sect4> section for each function that the previous text described in one long series of paragraphs. Also split the functions' previously in-line syntax summaries into <synopsis> clauses, which is more readable and allows us to sneak in an explicit mention of the result data type. This change gives us an opportunity to make cross-reference links more specific, too, so do that.
