contexthub: Make client registration API safer
Modifies the registration API for new endpoint session capabilities to
return a new dedicated IEndpointCommunication interface tied to the
client registration. All endpoint/session APIs have been moved to the
new interface. This prevents security issues resulting from pid re-use.
Adds an unregister() API to IEndpointCommunication for a client to
signal that its associated hub will no longer be active. Subsequent
calls on IEndpointCommunication APIs will fail.
