Rename NanostackRfPhy to NanostackPhy

This is to allow other types of PHY drivers than just RF.
Mesh-API does not actually care about driver type, it is drivers
responsibility to register right handlers with Nanostack.

* Implement a wrapper class NanostackRfPhy to ensure backward
  compatibility.
* Remove mesh_connect()/disconnect() functions from MeshInterface
  This job is already done in inherited classes.
* LoWPANNDInterface and ThreadInterface should only be used with
  NanostackRfPhy.
