  Log:
  Change the TCP timer system from using the callout system five times
  directly to a merged model where only one callout, the next to fire,
  is registered.
  
  Instead of callout_reset(9) and callout_stop(9) the new function
  tcp_timer_activate() is used which then internally manages the callout.
  
  The single new callout is a mutex callout on inpcb simplifying the
  locking a bit.
  
  tcp_timer() is the called function which handles all race conditions
  in one place and then dispatches the individual timer functions.
