Amey Inamdar d0c777b2e1 Protocomm : Added component core for protocol communication
* This manages secure sessions and provides framework for multiple transports.
* The application can use protocomm layer directly to have application specific extensions for provisioning (or non-provisioning) use cases.
* Following features are available for provisioning :

  * Security - Security0 (no security), Security1 (curve25519 key exchange + AES-CTR encryption)
  * Proof-of-possession support for Security1

* Protocomm requires specific protocol buffer modules for compilation which can be generated from the `.proto` files in the `proto` directory using make.
