if the minimum length of a response <tt>(1 + 2 + 16)</tt> is more than
the length claimed by
<tt>s->s3->rrec.length</tt>,
then return 0 without sending a heartbeat,
This will prevent trying to create a heartbeat when there's not enough
room to create a heartbeat at all.

Second, modify the code so that
if the minimum length of a response with a payload
<tt>(1 + 2 + payload + 16)</tt>
is more than the total length for a response given in
<tt>s->s3->rrec.length</tt> then again
return 0 without sending a h
