Change J-PAKE internal state machine

Keep track of the J-PAKE internal state in a more intuitive way.
Specifically, replace the current state with a struct of 5 fields:

* The round of J-PAKE we are currently in, FIRST or SECOND
* The 'mode' we are currently working in, INPUT or OUTPUT
* The number of inputs so far this round
* The number of outputs so far this round
* The PAKE step we are expecting, KEY_SHARE, ZK_PUBLIC or ZK_PROOF

This should improve the readability of the state-transformation code.
