Work on fragments in layouts. 

- Change semantics if IDs associated with these fragments, to
  work correctly when placed in a container.  If the container
  has an ID or you have supplied a tag, the fragment's ID is
  optional.

- To do this, there is a new LayoutInflater API that allows code
  creating views to access the parent container that view will
  be in.

- Fix issues with state management around these fragments.  Now
  correctly retains state when switching to a layout that doesn't
  include the fragment.

Also:

- Add new simple list layouts for items that want to show an
  activated state.
- Add new Activity.dump() that can be invoked with adb shell
  dumpsys; the default implementation dumps fragment state.
