Summary:Set `Touchable.TOUCH_TARGET_DEBUG` to see colored borders/text to all touchables.
Different touchable types are color-coded differently.
If there is `hitSlop`, it will be rendered with an extra view with a dashed border of the same color (not visible on
Android because `overflow: 'hidden'`).
`Text` with `onPress` directly set is just colored.
Added some extra checks to `TouchableWithoutFeedback` since it could silently break if the child is not a native
component.
Also added better error output for `ensureComponentIsNative` so it's easier to track down issues. I really wish there
was a cleaner way to get the component and owner names consistently, it would help make good debug messages way easier
to write.

I split them up manually.
Then I replaced the React = require('react-native') + destructuring pattern...
```
(?s)(const|var)\s+React\s*=\s*require\('react\-native'\)(.*[^\{\}]*\}\s*=\s*)React;
```
...with...
```
$1 React = require('react');
$1 ReactNative = require('react-native')$2ReactNative;
```
I used lint to figure out if I left some unnecessary imports.
Finally I grepped for just
```
React\s*=\s*require\('react\-native'\)
```
to catch any remaining patterns.
Also, `} = React.NativeModules` -> `} = ReactNative.NativeModules`.

Summary:**Motivation**
Multiple instances of `Text` inside a `ListView` is a bad idea for the performance of the app.
When you create 1000 elements and you scroll through the list it is really slow and laggy because the `NSTextStorage`, which is the backbone of the `RCTText` element, will set more than 1,000 times and also the method `setNeedsDisplay` is called multiple times. This will causes huge memory problems and the app crashes.
With this commit I check in `RCTText` if the `NSTextStorage` differs from the old value. If yes then set it otherwise don't set the `NSTextStorage`. This will prevent to call `setNeedsDisplay` when not really needed.

This diff adds support for auto-resizing multiline text fields. This has been a long-requested feature, with several native solutions having been proposed (see https://github.com/facebook/react-native/pull/1229 and D2846915).
Rather than making this a feature of the native component, this diff simply exposes some extra information in the `onChange` event that makes it easy to implement this in pure JS code. I think this is preferable, since it's simpler, works cross-platform, and avoids any controversy about what the API should look like, or how the props should be named. It also makes it easier to implement custom min/max-height logic.

Summary:

React Native currently exposes the iOS layer shadow properties more-or-less directly, however there are a number of problems with this:
1) Performance when using these properties is poor by default. That's because iOS calculates the shadow by getting the exact pixel mask of the view, including any tranlucent content, and all of its subviews, which is very CPU and GPU-intensive.
2) The iOS shadow properties do not match the syntax or semantics of the CSS box-shadow standard, and are unlikely to be possible to implement on Android.
3) We don't expose the `layer.shadowPath` property, which is crucial to getting good performance out of layer shadows.
This diff solves problem number 1) by implementing a default `shadowPath` that matches the view border for views with an opaque background. This improves the performance of shadows by optimizing for the common usage case. I've also reinstated background color propagation for views which have shadow props - this should help ensure that this best-case scenario occurs more often.
For views with an explicit transparent background, the shadow will continue to work as it did before ( `shadowPath` will be left unset, and the shadow will be derived exactly from the pixels of the view and its subviews). This is the worst-case path for performance, however, so you should avoid it unless absolutely necessary. **Support for this may be disabled by default in future, or dropped altogether.**
For translucent images, it is suggested that you bake the shadow into the image itself, or use another mechanism to pre-generate the shadow. For text shadows, you should use the textShadow properties, which work cross-platform and have much better performance.
Problem number 2) will be solved in a future diff, possibly by renaming the iOS shadowXXX properties to boxShadowXXX, and changing the syntax and semantics to match the CSS standards.
Problem number 3) is now mostly moot, since we generate the shadowPath automatically. In future, we may provide an iOS-specific prop to set the path explicitly if there's a demand for more precise control of the shadow.

Summary:
public
Blending semitransparent pixels against their background is fairly a fairly expensive operation on mobile GPUs. To reduce blending, React Native has a system called "background color propagation", where the background color of parent views is automatically inherited by child views unless explicitly overridden. This means that translucent pixels can be blended directly against a known background color, avoiding the need to do this dynamically on the GPU.
In practice, this is only useful for views that do their own drawing, which is basically just `<Image/>` and `<Text/>` components, and for image components it only really matters when the image has an alpha component.
The automatic background propagation is a bit of a hack, and often does the wrong thing - for example if a view overflows its bounds, or if it overlaps a sibling, the background color will often be incorrect and need to be manually disabled. Because the only place that it provides a significant performance benefit is for text, this diff disables the behavior for everything except `<Text/>` nodes. It might still be useful for `<Image/>` nodes too, but looking through the examples in UIExplorer, the number of places where it does the wrong thing for images outnumbers the cases where it provides significant reduction in blending.
Note that this diff does not prevent you from eliminating blending on image components by manually setting an opaque background color, nor does it stop you from disabling color propagation on text components by manually setting a transparent background.

Most apps create tons of text components but they are actually quite heavy because of the the Touchable mixin which requires binding tons of functions for every instance created.
This diff makes the binding lazy, so that the main handlers are only bound if there is a valid touch action configured (e.g. onPress), and the Touchable mixin functions are only bound the first time the node is actually touched and becomes the responder.
ScanLab testing shows 5-10% win on render time and memory for various products.

Setting `blurOnSubmit=true` on a multiline `<TextInput>` now causes it to behave like a single-line input with respect to the return key:
With the default value of `false`, pressing return will enter a newline character into the field. If you set the value to `true`, pressing return will now blur the field and trigger the onSubmitEditing event. The newline character will *not* be added to the text.
