EC J-PAKE context structure.

J-PAKE is a symmetric protocol, except for the identifiers used in Zero-Knowledge Proofs, and the serialization of the second message (KeyExchange) as defined by the Thread spec.

In order to benefit from this symmetry, we choose a different naming convetion from the Thread v1.0 spec. Correspondance is indicated in the description as a pair C: client name, S: server name
