Automated g4 rollback of changelist 160202511.

*** Reason for rollback ***

Causes crash, see b/63127884

*** Original change description ***

All Fragments are now support library Fragments.

Switch a bunch of imports to support library Fragments (and Loaders) instead of framework Fragments (and Loaders). This was needed to use FragmentManager.isStateSaved() instead of manually tracking that state. This should reduce errors around committing after state is saved.

Also adds METADATA presubmit to prevent new usages of framework Fragments or Loaders.
