Prevents ListView items children to modify properties of other children.
Bug #2464502

This fix introduce a new dispatch mechanism to tell views when they are temporary
detached/reattached from/to a ListView. This is very important to remove pending
callbacks or cleanup temporary states.

This change also modifies TextView which was relying on that callback in a very
particular case: a focused EditText in a ListView. The modified code acts only
when in that case, not if onStart/FinishTemporaryDetach() is called via
dispatch*() (== recycled views in ListView.)
