A very simple way out of headlocks, besides the obvious - not getting into one, is simply to pop the elbow with simultaneously pulling the head out. I used this for wrestling alot it is a great counter set-up as well.
Also, a head-lock is just that it does not (should not ) involve the trachea or corotid (neck). So in truth it cannot be a form of choke.
The front headlock and Guillitine are different techniques with different objectives.
