A few small changes that didn't seem to deserve separate commits: - Mark it as packed to remove compiler complaints when it's a member of a packed struct. - Add a default constructor for places where we fill in a struct gradually. - Restrict the constructor to exactly 4-character string literals. - Add a to_u32() method for the one place that needs that.
