Summary:
Everything (but Views) are drawn using AbstractDrawCommand (or its derivative, like DrawBorder or DrawBackgroundColor) and supports clipping properly. Views however are drawn using an assumption that Android will clip them manually. This is however not always true. One example is if an element A mounts to a View, and its parent B doesn't but has overflow: hidden and thus should clip the child.
There are 2 ways to fix this:
- pop every element that has overflow: hidden to its own View. In this case, its children will always be correctly clipped. This is however very inefficient, especially if overflow: hidden is default (which it is!) which means that almost every React element must be backed by an Android View.
- add clipping information to DrawView, similar to how AbstractDrawCommand has it.
This diff implements the latter approach.

Summary: RootFlatShadowNode always mounts to a (top-level) View but was never marked as one that mounts to a View. This diff fixes it. Nothing in the code relied on it being marked as mounting to a View, so it worked fine. A follow up path that implements UIImplementation.measure() for nodes that don't mount to a View goes up until it finds first mounting node, and it was crashing with NPE because it tried to access RootFlatShadowNode's parent (and there isn't one).

Summary: D2768643 disabled View clipping of FlatViewGroup's children by calling setClipChildren(false). Turns out, instead of disabling clipping on the View this method is called on, it disables clipping on the children, instead. While we want the clipping disabled on all children that are FlatViewGroups, it also means that everyone else gets the clipping disabled as well. This has issues with ScrollView that stopped clipping its scrolling content, resulting in visual glitches. To fix the issue, manually clip all the Views that are not FlatViewGroups.

Summary: AbstractDrawCommand's bounds are supposed to be the rectangle that the DrawCommand will draw into, so that it can compare bounds against clip rect bounds and reliable skip clipping when it's not needed. It is however not true for RCTText that can create text Layout that in some cases can go out of it's requested bounds (happens with TextView, too). To fix the issue, instead of passing requested bounds, pass the actual ones. In this case, AbstractDrawCommand will make sure to clip DrawTextLayout if for some reason it draws outside of the allowed boundaries.

Summary:
@public React allows excluding certain elements from touch handling by assigning `PointerEvents` filter to them, such as BOX_NONE - this element will not receive touch but its children will, BOX_ONLY - only this element will receive pointer event and not children, NONE - neither this element nor its children will receive pointer events, and AUTO - pointer events are allowed for both this element and its children.
This diff adds PointerEvents support to flat RCTView. Most of the implementation is copied from ReactViewManager/ReactViewGroup. One small change is made to TouchTargetHelper to ensure that it works correctly with virtual nodes when their parent has PointerEvents set to PointerEvents.BOX_NONE.

Summary:
Prior to this patch DrawCommands weren't get clipped by parent DrawCommands at all. For example, a <View> element with size 200x200 with overflow:hidden should clip its child which is 400x400, but this didn't happen. However, if parent <View> would mount to an Android View, it would clip the child regardless of the overflow attribute value (because Android Views always clip whatever is drawing inside that View against its boundaries).
This diff is fixing these issue, implementing overflow attribute support and making clipping behavior consistent between nodes that mount to View and nodes that don't.

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:
In ReactNative, we are fully controlling layout of all the Views, not allowing Android to layout anything for us. This is done by making onLayout() of the top-level View in the hierarchy to be empty. This works fine because we explicitly call measure/layout for all the Views when they need to be re-measured or re-laid out. There is however one case where this doesn't happen automatically: some Android Views such as DrawerLayout or ActionBar have children that don't have shadow nodes associated with them (such as a title in ActionBar). This results in situations where children of AndroidView will call requestLayout but they will never get relaid out, because shadow hierarchy doesn't know about them. Example: ActionBar has a seTitle method that will internally call TextView.setTitle() and that TextView will call requestLayout because its size may have changed. However, that TextView will never be remeasured or relaid out.
This diff is fixing it by keeping track of everyone who called requestLayout. Then, at the end of the update loop we go over the list a manually remeasure and relayout those Views.
Not a huge fan of how this is implemented (there MUST be a better way) but this works with least efforts. I'll see if I can improve it later.

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: Normally, order or `measure/layout` and `onAttachedToWindow` shouldn't matter. However, `DrawerLayout` has a `boolean mFirstLayout` flag that it resets to true in `onAttachedToWindow` that makes it ignore first layout, and it leads to bugs. To fix the issue, we need to make sure that we first call `onAttachedToWindow` and only then we call `measure/layout`. The easiest way to do it is to delay measure/layout calls until all the views are attached to their parents. This diff implements the mentioned logic.
