Doc: improve documentation about random(). We didn't explicitly say that random() uses a randomly-chosen seed if you haven't called setseed(). Do so.
Also, remove ref/set.sgml's no-longer-accurate (and never very relevant) statement that the seed value is multiplied by 2^31-1. Back-patch to v12 where set.sgml's claim stopped being true. The claim that we use a source of random bits as seed was debatable before 4203842a1, too, so v12 seems like a good place to stop. Per question from Carl Sopchak.
