This allows an app to show a voice search button
and invoke a voice interaction session for use
within the activity. Once the activity exits, the
session is stopped.
Test application has a new activity that
demonstrates it with the test voice interaction
service.
This initial version is functional enough for
an integration test, with some more tests
and improvements to come later.

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.
