Add fdprintf(). Remove reread() and rewrite() which handle -EINTR, which shouldn't be a problem if we register signal handlers with sigaction(SA_RESTART) Straighten out count and len (I generally consistently use "count" for the current progress and "len" for the total, but this time I got them backwards for some reason and don't want to confuse myself in future.)
