      stun timer: fix timeout of the last retransmission · f6f704c5
      Fabrice Bellet authored
      According to RFC 5389, section 7.2.1, a special timeout is applied to
      the last retransmission (Rm * RTO), with Rm default value of 16, instead
      of (64 * RTO), 2^6 when the number of transmissions Rc is set to 7.
      
      As spotted by Olivier Crete, stun_timer_* is a public API, that cannot
      be changed, and the initial delay (RTO) is not preserved in the
      stun_timer_s struct. So we use a hack that implicitely guess Rm from the
      number of transmissions Rc, by generalizing the default value of the
      spec for Rm and Rc to other values of Rc passed in stun_timer_start(
      
      According to the spec, with the default value of Rc=7, the last delay
      should be (64 * RTO), and it is instead (16 * RTO). So the last delay
      can be computed by dividing the penultimate delay by two, instead of
      multiplying it by two.
