In 3e the Factorum had cunning surge, which allowed it to spend 3 inspiration points to take an extra standar action. That seems to be the common ancestor to 4e action points and 5e action surges.
OK, so Action Surge (5e fighter) <- Action Points (4e) <- Cunning Surge (3e Factotum),Eberron Action Points are very different than 4e Action Points. Long story short; they add 1-6 to a d20 roll, not an extra action.
but Bardic Inspiration/Hero Points (5e) <- Action Points (3e Ebberon) <- Action Points (d20 Modern) <- Force Points (d20 SW).
I'm a little disappointed to tick off another thing I'd been thinking was a 5e innovation.

That about sums it up.Which, to be sure, isn't a surprise considering the "Greatest Hits" type of edition 5e is.
