Summary:
React allows nesting <Image> inside <Text>, in which case it turns into an RCTTextInlineImage element. RNFeed is using it in a few places and thus we need to support it, too.
This diff implements it with InlineImageSpan (WithPipeline, and WithDrawee separately).

Summary: When setJSResponder() is called on a shadow node that doesn't mount to a View, React runtime will crash in NativeViewHierarchyManager because it will fail to find a corresponding View. To fix the issue, make sure we forceMountToView() before we call enqueueSetJSResponder().

Summary: Previously, manageChildren() would throw an Exception if moveFrom != null or moveTo != null. This is obviously not correct, because no matter how rare these events are, they actually happen in practice. This diff re-implements manageChildren() to support all the cases. It does so by first removing all the elements that need to be removed. During removal, those elements that need to be moved will be temporarily put into `mNodesToMove` array. Then the next step is to add all elements (including new elements to add, and existing elements to move). There is an fast path when only one of another is present. If both types are present, they need to be sorted, first, to maintain correct orded. A similar optimization is applied to `removeChildren()`: there is a fast path when moveFrom == null and a another fast path when removeFrom == null. When both are != null, a merge sort is used (it is assumed that both moveFrom and removeFrom are sorted).

Summary: There is an OnLayoutEvent that needs to be dispatched when a ReactShadowNode gets re-laid out. Some applications rely on it, so we should support it. This diff adds this functionality.

Summary:
There is currently a bug where we never release any Views that no longer display, still storing hard references in NativeViewHierarchyManager. This diff is fixing this bug, and here is how:
a) there is already logic in place to drop FlatShadowNodes (UIImplementation.removeShadowNode).
b) there is already logic in place to drop Views (NativeViewHierarchyManager.dropView(int reactTag) - used to private but needs to be protected so I can call it)
c) (the missing part) when we are about to drop a FlatShadowNode, check if it mount to a View (i.e. there is a View associated with that node), put it into a ArrayList. When we finished updates to a nodes hierarchy (which happens in non-UI thread), collect ids from those nodes and enqueue a UIOperation that will drop all the Views. We can either forward nodes as FlatShadowNode[], or only ids as int[]. Both should be fine, but as a rule of thumb we don't touch shadow node hierarchy from UI thread (as we don't touch Views from non-UI thread) so passing int[] is what this code is doing.

Summary: This diff adds an `AndroidView` as a proxy for custom Views in FlatUIImplementation. Any ReactShadowNode that FlatUIImplementation doesn't recognize (because they don't extend from FlatShadowNode) will be wrapped with AndroidView to ensure that it measures and displays correctly. While not perfect, this is the easiest way to support custom Views (EditTexts, DrawerLayouts, ScrollViews etc).

Summary: @public There are some properties, such as alpha or scale that we ONLY handle on a View level. This means that whenever we encounter a FlatShadowNode with this property, it should be mapped to a View. This diff is doing exactly this.

Summary: @public There are some properties that we want to handle on a View level, as opposed to a FlatShadowNode level. For example, scale or alpha, that can be done very efficiently in hardware. Once we pop FlatShadowNode to a separate View, we need to apply these properties. This is where `BaseViewManager` comes in handy.

Summary: @public This patch adds basic support for RCTImageView (only 'src', 'tintColor' and 'resizeMode' properties are supported for now), and a concept of AttachDetachListener that is required to support it to FlatUIImplementations.
