Summary:
Virtual shadow nodes (e.g. text) don't use CSSNodes so we don't need to create them. This shows large savings in CSSNodes allocated, depending on the app.
This could be breaking if:
- You have virtual nodes that still set and get CSS properties. The setters now no-op for virtual nodes (I unfortunately couldn't remove them completely -- see the comment on LayoutShadowNode), but the getters will NPE. If you see these NPE's, you should almost definitely be using your own datastructure instead of a CSSNode as virtual nodes will not participate in the layout process (and the CSSNode is then behaving just as a POJO for you).
I do not anticipate this to be breaking for anyone, but am including breaking in the commit message since this is a change in API contract.

Summary:
**Motivation**
In the context of a webview, one may extract assets (javascript or any types really), and relates to them through the html.
The packager `Server` serves this files correctly but also applies a cache based on time (a year). During development, this cache is actually bad as we need to re-iterate the process of editing/testing quickly.
I don't believe it is necessary to cache, and still wanted to make sure we would if process.env.NODE_ENV is 'production'.
**Test plan**
Run jest on impacted files:
```
node_modules/.bin/jest packager/react-packager/src/Server/__tests__/Server-test.js
```

Summary:
When tapping on a link in a WebView with an unknown scheme, the app would crash. For example, if you have the link "something://example/" but your device doesn't have anything to handle the "something" scheme, the app would crash when the user clicks on the link. This change handles the exception to prevent the app from crashing. Instead, the click is a no-op and the WebView doesn't navigate anywhere.
**Test plan (required)**
Verified the app no longer crashes when clicking on unknown schemes in a test app. Also, my team uses this change in our app.

Summary:
The only callsite of `coalesce` looks like this:
```
newEvent.coalesce(oldEvent);
```
The default `coalesce` implementation returns the event with the most recent timestamp. When the events have the same timestamp then, using the variable names from above, `coalesce` returns `oldEvent`.
This change updates `coalesce`'s implementation to make it explicit that it returns `this` (`newEvent` in the variable names from above) in the case of a tie.
The motivation for this change is related to scroll events. In my team's app, we were seeing scroll events being emitted with the same timestamp and the coalescing logic was causing the oldest scroll event to be chosen. This was causing our JavaScript code to receive stale scroll information and the way the JavaScript code utilized this stale scroll information resulted in the ScrollView settling on the wrong scroll position.
**Test plan (required)**
Verified that scroll events work properly in a ScrollView in a test app. Also, my team's app uses this

**Motivation**
ncuillery Is has a lot of experience with upgrading RN projects (see his [talk](http://www.slideshare.net/ncuillery/introducing-the-new-reactnative-upgrade)) and is rewriting 'react-native upgrade' to use git.
He tells me that we actually want git to merge changes in the .pbxproj file. In his words: "Making the project.pbxproj invisible for "git diff" means that react-native-git-upgrade will never be able to upgrade the project.pbxproj."
Note the git docs explicitly recommend not to use git to merge .pbxproj files: https://git-scm.com/book/en/v2/Customizing-Git-Git-Attributes#Binary-Files
ncuillery do we have an alternative? Some ideas:
1. Use a 3rd-party tool in 'react-native upgrade' to merge the .pbxproj file?
2. We could always re-generate and overwrite the .pbxproj file (never merge) and then run 'react-native link' to update native 3rd-party dependencies in the Xcode project?
3. Last resort: stay away

As said in #10944, there's not yet some good infos on how to profile the javascript.
I'm adding a mention to two ways of doing it (`react-addons-perf` and chrome profiler), feel free to correct me on this.
I almost added an example for `react-addons-perf` but I'm not sure what's the correct way to use. Here's the way I use it:
```javascript
import Perf from 'react-addons-perf';
....
componentDidMount() {
console.log('start perf tracking');
Perf.start();
setTimeout(() => {
console.log('stop perf tracking');
Perf.stop();
Perf.printExclusive();
}, 10000);
}
...

Summary:
TextInput rounds padding down with `floor` when measuring. However, it rounds padding up with `ceil` when rendering.
This change makes things consistent by moving TextInput's rendering code to use `floor` as well. It looks like this is the intended behavior because commit bdff10b moved measuring from `ceil` to `floor`. It looks like TextInput's rendering code was just overlooked in that commit.
**Test plan (required)**
Verified TextInput padding works in a test app. Also, my team uses this change in our app.

Summary:
When running in strict mode we run into the following error:
“Cannot assign to read only property 'product' of object '#<WorkerNavigator>’”
Moreover navigator.product = ‘ReactNative’; didn’t actually change the product value. Without strict mode this was silently ignored.
By using our defineProperty function we are able to run in strict mode and now navigator.product is really ReactNative.
See https://github.com/facebook/react-native/issues/10881 for more information
---------------
Long story short - if we run in strict mode, the current code throws an error :
`Cannot assign to read only property 'product' of object '#<WorkerNavigator>' initializeCore.js`
(the current version of initializeCore.js doesn't have 'use strict'; on top, but if you are unfortunate enough to have a babel module that ads this for you, you are guaranteed to run into this. Moreover our contributing guidelines say that we should have 'use strict'; https://github.com/facebook/react-native/blob/master/CONTRIB

Summary:
Moves from CSSNodeDEPRECATED to CSSNode. This has shown to be a huge performance win for layout time within FB.
This is BREAKING because CSSNode contains bug fixes that were not migrated to CSSNodeDEPRECATED which may change the way your layout appears. The most common of these by far involves `flex: 1`.
Previously, developers had to put `flex: 1` in many places it didn't belong in order to work around a bug in css-layout. Now `flex: 1` is treated properly and, unfortunately, this means that your layout may no longer look correct. Specifically, you may see that your layout looks collapsed, or children don't render. The fix is to simply remove `flex: 1` from those containers.
