Summary: Concolidate the creation of the "update payload" into
ReactNativeAttributePayload which now has a create
and a diff version. The create version can be used by
both mountComponent and setNativeProps. This means that
diffRawProperties moves into ReactNativeAttributePayload.
Instead of storing previousFlattenedStyle as memoized
state in the component tree, I recalculate it every
time. This allows better use of the generational GC.
However, it is still probably a fairly expensive
technique so I will follow it up with a diff that
walks both nested array trees to do the diffing in a
follow up.
This is the first diff of several steps.

Sometimes we want to load a very small number of rows initially and want the
onEndReached callback to be called immediately to trigger more data to be
loaded without waiting for the user to scroll at all. This diff makes that
happen by also checking on mount instead of only when scrolling.

Summary: The StyleSheet merging algorithm was modeled after `Object.assign` and the native spread operator. This diff converts `flattenStyle` to actually use `Object.assign`.

Jest has an issue where if you export `Symbol` it crashes badly. Since event-target-shim does that, it breaks everything. Mocking that module fixes the issue until @cpojer comes back from vacation and fixes the bug in Jest itself.

Summary: I previously added this check to make the test complete waits until all teardown completed but if you're running tests with any other executor than the JSC one, this would crash.

Summary: **Problem**
Using push notifications in IOS 8 will throw this error:
`registerForRemoteNotificationTypes: is not supported in iOS 8.0 and later.`
The problem is that the check is running on compile instead of runtime.
**Solution**
If have changed the compile if statement to a runtime if statement. The fix is tested on: IOS 7.1 and 8.* and everything is working now.
This solution is also discussed in: https://github.com/facebook/react-native/issues/1613 and it was part of https://github.com/facebook/react-native/pull/1979. (is being separated to keep things moving)
Please let me know what you think.Closes https://github.com/facebook/react-native/pull/2332

Summary: When `RCTImageView` is removed from the view hierarchy, it clears out its `image` to save memory. This makes sense, except that it gets removed from the window (view hierarchy) even when becoming the child of another view.
This fixes the logic so that it only clears out the image if the view hasn't been moved somewhere else within one frame.

It's less important to reload for downscaling than upscaling, so increase the threshold in that direction. Also, this now considers each dimension separately, and a big enough change either way should result in a reload.
Finally, this considers both the current image size and the inflight target size, so we don't reload if either is already good.
