Voice Interaction from within an Activity

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.
