This makes VoiceInteractionSession a more first-class
concept. Now the flow is that a VoiceInteractionService
calls startSession() when it wants to begin a session.
This will result in a new VoiceInteractionSession via the
VoiceInteractionSessionService containing it, and the
session at that point an decide what to do. It can now
show UI, and it is what has access to the startVoiceActivity
API.

On the app side, requests are now composed by subclassing
from various types of Request objects.
On the service side, starting a voice interaction session
involves starting another service that will then manage the
session. This leads the service design much more to what
we want, where the long-running main service is very tiny
and all the heavy-weight transient session work is elsewhere
in another process.

This gives a basic working implementation of a persist
running service that can start a voice interaction when
it wants, with the target activity(s) able to go through
the protocol to interact with it. It may even work when
the screen is off by putting the activity manager in the
correct state to act like the screen is on.
Includes a sample app that is a voice interation service
and also has an activity it can launch.
Now that I have this initial implementation, I think I
want to rework some aspects of the API.
