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.)
