commit 092d14cd22c174405221b930665869f7c9fc8b65
Author: Ian Lake <ilake@google.com>
Date:   Tue Aug 27 14:46:02 2019

    Remove FragmentState mInstance
   
    Make FragmentState a simple Parcelable by removing
    its mInstance field and its instantiate() method.
   
    This required we change the order of restoring:
    instead of reconnecting retained Fragments with their
    FragmentState instances, we first iterate through
    all FragmentState instances and do one of two things:
    1) Reconnect the retained fragment if it exists
    2) Create a new fragment from the FragmentState
   
    This allows us to do just one pass through our
    FragmentState objects and run the edge case of
    detecting retained fragments created after the
    state was saved after creating the set of active
    fragments.
   
    Test: all existing tests pass

commit bef266f3ab8734afc111c70413687380ad2d9161
Author: Ian Lake <ilake@google.com>
Date:   Tue Oct 01 11:04:33 2019

    Move create/destroy to FragmentStateManager
   
    Due to restoreSaveState()'s cleaning up
    of no longer valid retained Fragments, moveToState()
    now always creates a FragmentStateManager if one
    does not exist so that we can continue to run the
    create callbacks despite these retained Fragments
    not being in mActive.
   
    Interactions with mExitAnimationCancellationSignals
    as part of destroying the Fragment remain in
    moveToState() for now.
   
    Test: Fragment tests still pass

Author: Ian Lake <ilake@google.com>
Date:   Tue Oct 01 10:49:06 2019

    Move restoreState() out of moveToState()
   
    We can safely call restoreState() immediately
    after creating a FragmentStateManager instance
    rather than waiting for moveToState().
   
    This simplifies the logic required since
    we know we'll have the correct value of
    mDeferStart before computeMaxState().

    Dispatch manager state changes to FragmentStateManagers
   
    Instead of assuming that a FragmentStateManager
    can go up to RESUMED by default, dispatch the
    FragmentManager's state changes to each
    FragmentStateManager and use that to set
    the maximum state of the FragmentStateManager.
   
    The one exception is when using the <fragment>
    tag, which allows Fragments to move to CREATED
    before the FragmentManager itself moves to
    CREATED.

    Move add/removeRetainedFragment logic to non config
   
    Instead of splitting the logic of
    add/removeRetainedFragment between FragmentManager
    and FragmentManagerViewModel (the non config),
    move it all to non config.
   
    This requires forwarding signals on whether the
    state is saved to FragmentManagerViewModel so
    that it can properly ignore changes after the
    state is saved.
   
    Test: newly added tests pass

    Move remaining attach logic to FragmentStateManager
   
    Use FragmentStateManager's access to FragmentStore
    and its moveToExpectedState() to move all of the
    logic for moving to the attached state to
    FragmentStateManager.
