Summary: There are cases where we're trying to drop a view that is not associated with a ViewManager. This is likely caused by race conditions that can occur if we're dropping a view from JS (when it's no longer used) but at the same time dropping it from native (when layout animation ends, when the rootview gets unmounted). In either of those cases, it should be safe to ignore the drop operation because the view was likely dropped already.

Currently only parent can tell the layout to align its children based on baseline. But if one of the children is a column or row then basealign does not work as expected.
We have added an api setReferenceBaseline which when set to true would mean that it's baseline would be considered as the reference baseline for parent amongst its siblings. If there are more than one siblings with referenceBaseline set, the first one would be considered.

Summary:
Yet another issue with mAttachedRootViews. Every time attachRootView is called, the root view's id is reset to NO_ID. However, there can be a case where the react context has not initialized yet, so we delay attaching the root view to the instance manager until setupReactContext. If attachRootView was called a second time before the react context has finished initializing, we end up in a situation where we try to attach the same root view twice
I'm planning to remove mAttachedRootViews all together in a future diff, but for now let's avoid these crashes.

D12829677 introduced a deadlock where onHostResume holds the lock on `moveToResumedLifecycleState()` then waits for the `mReactContext` lock, but at the same time setupReactContext holds the `mReactContext` lock and waits for `moveToResumedLifecycleState()` https://our.intern.facebook.com/intern/everpaste/?handle=GAgXFgLQH1ZlQikBAMQzo2LZ6h9TbiAxAAAz. The purpose of the previous diff was to make sure that detachRootoView and
setupReactContext did not interfere with each other, and implemented that by blocking on mReactContext. Since this overloads the usage of mReactContext, let's use a different lock `mAttachedRootViews` to implement this behavior instead

Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:
Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```
updateLayoutMountItem for reactTag: 420006 x: -440, y: -13, width: 931, height: 78
updateLayoutMountItem for reactTag: 420010 x: 26, y: 79, width: 0, height: 1651

Summary:
There are multiple reports of the NativeViewHierarchyManager trying to remove a root view with id -1. This can occur because of a race condition caused by calls to startReactApplication + unmountReactApplication.
We unfortunately overload overload the id field of the ReactRootView to store its react tag. This id is typically set when the view is attached to the react instance, and reset to NO_ID right before an attach occurs or when the react context is tearing down. If the react context has already been initialized, attaching the root view is synchronous and the id is set immediately. If the context has not been initialized, we save the root view in a mAttachedRootViews list and wait until setupReactContext (where the context is created) to finish attaching the root views.
There were two issues:
1) In setupReactContext, synchronizing on mReactContextLock is not enough to ensure that the root views in mAttachedRootViews have been initialized already
2) In detachRootView, removing the root view from mAttachedRootViews immediately will cause mAttachedRootViews to be out of sync when it is accessed by the time it is accessed in setupReactContext
To address these, the mReactContextLock will synchronize both the creation of the react context AND the initialization of the root views and detachRootView will synchronize on the mReactContextLock before mutating the mAttachedRootViews list.

------
1. New folly will have build break for a gcc-4.9 and gcc-4.9 seems to be deprecated for latest folly.
As we only use partial folly implementations, I just fixed the build break part.
To support building RN on Windows, the patches are written by gradle ReplaceTokens.
2. The change for glog copying header into exported/ is to prevent build break for folly.
`folly/detail/Demangle.h` will try to use libstdc++'s demangle.h. Unfortunately, glog also has a demangle.h in source code. So I copy exported headers and only search headers in exported/ folder during build.

* The `delta` property is renamed to `modules`.
* Deleted modules are now listed inside of the `deleted` property, which is only defined by `DeltaBundle`.

This crash seems to be happening because the root view's id is set to a non NO_ID value, but further up in the stack trace, UIManager.addRootView() is called which always sets the root view's id to NO_ID. It's not clear how this error is happening, but in this code path it's expected that addRootView should always ensure that the id is always reset. In order to avoid crashing for this, let's remove the exception and log the issue instead.
In the future, we should not be overloading the android view id field with these types of react native implementation details. The react tag should be stored as a view tag instead.

Summary:
This diff includes a few changes:
1. Move the headers inside `jsiexecutor` into `jsiexecutor/jsireact`. As far as I'm aware, the Android ndk build system isn't flexible enough to support header namespaces, so we can't just expose the headers inside the `jsiexecutor` directory under the `jsireact` namespace. Therefore, I moved the headers to `jsiexecutor/jsireact`, and added `jsiexecutor` to the header search path. This was the easiest way to simulate `jsireact` namespace.
2. Setup the Android.mk files to get RNTester compiling and running.
3. Introduce a `jscexecutor` module to make `JSCExecutor.java` execute without throwing.
**Note:** Moving the header files inside `jsiexecutor` probably breaks the iOS builds and internal builds. I'll fix those in subsequent diffs on this stack.
