Summary:
Hello,
This PR adds a property to the `ListView` to enable and disable to sticky sections headers behaviour. Current this is enabled by default and there is no way to disable it. It has been previously discussed in #1974 where there was a suggestion to add the `ListView` inside `ScrollView`. This is bad for performance, but some people were using that as a workaround. satya164 suggested someone submitting a PR, which is why I'm here 😉
I have tested the property manually by adding `stickySectionHeaders={false}` to the `<ListView> Paging` example in `UIExplorer`. I have also tested that the current behaviour still stands, so this is a non-breaking change.
I have also checked that the website displays the new documentation.
I couldn't see anywhere to add automated tests to this, but if there is feel free to point it out and I'll update this PR.
I tried running `npm run lint` to check the code style, but it spat out loads and loads of errors. I presume I have something set up incorrectly. Feel

:( this confused me, I thought I was missing some configuration or something. But the UIExplorer app has sticky headers on iOS, and non-sticky headers on Android, so I guess that's that.

"The single rest at the end only applies to binding `let { x, ...y } = obj;` and assignment `({ x, ...y } = obj).`"
I'd say this really should be cherry picked into the stable branch.

Summary:Fixes an issue where if you implement `renderScrollComponent` and have a `ref` callback on the returned element, the ref used to be clobbered by the ref that ListView adds to the element.
This is accomplished by converting the ref from a legacy string-based ref to a callback-based ref, and then using `cloneReferencedElement`, which is a simple utility to compose callback refs.

Summary:The website now displays public methods on components. This was implemented mostly in react-docgen via #66. This adds a <Method> component that is used by the component and API doc pages to display documentation for a method.
It also adds some missing documentation and tweak some existing one to integrate with this feature. I also prefixed some component methods with an '_' so they don't show up in the doc.
**Test plan (required)**
Tested every component page locally to make sure the methods doc was displayed properly.
Tested an API page to make sure it still worked properly.

Summary:Since the React 0.14 split of modules, the findNodeHandle feature is part of the
renderer and not the generic React API.
This just greps for React.findNodeHandle and replace them with ReactNative.findNodeHandle. I fixed up the imports manually.
I also found two callers each of ReactNative.createClass and React.render with the exception of downstream and examples will fix them separately.
I'll need to find more things like `var { PropTypes } = ReactNative;` separately. I think this is a good start though.

Summary:
public
I was looking into the missing panels at the bottom of the <ListView> - Grid Layout example, and found that it was caused by several problems, some in the example and some in ListView itself.
The first problem seemed to be a bug in the `_getDistanceFromEnd()` method, which calculates whether the ListView needs to load more content based on the distance of the visible content from the bottom of the scrollview. This was previously using the function
Math.max(scrollProperties.contentLength, scrollProperties.visibleLength) - scrollProperties.visibleLength - scrollProperties.offset
to calculate the amount the user could scroll before they run out of content. This sort-of works in most cases because `scrollProperties.contentLength` is usually longer than `scrollProperties.visibleLength`, so this would generally evaluate to
scrollProperties.contentLength - scrollProperties.visibleLength - scrollProperties.offset
which meant that it would be positive as long as there was content still to be displayed offscreen, and negative when you reached the end of the content. This logic breaks down if `contentLength` is less than `visibleLength`, however. For example, if you have 300pts of content loaded, and your scrollView is 500pts tall, and your scroll position is zero, this evaluates to
Math.max(300, 500) - 500 - 0 = 0
In other words, the algorithm is saying that you have zero pts of scroll content remaining before you need to reload. But actually, the bottom 200pts of the screen are empty, so you're really 200pts in debt, and need to load extra rows to fill that space. The correct algorithm is simply to get rid of the `Math.max` and just use
scrollProperties.contentLength - scrollProperties.visibleLength - scrollProperties.offset
I originally thought that this was the cause of the gap, but it isn't, because ListView has `DEFAULT_SCROLL_RENDER_AHEAD = 1000`, which means that it tries to load at least 1000pts more content than is currently visible, to avoid gaps. This masked the bug, so in practice it wasn't causing an issue.
The next problem I found was that there is an implict assumption in ListView that the first page of content you load is sufficient to cover the screen, or rather, that the first _ second page is sufficient. The constants `DEFAULT_INITIAL_ROWS = 10` and `DEFAULT_PAGE_SIZE = 1`, mean that when the ListView first loads, the following happens:
1. It loads 10 rows of content.
2. It checks if `_getDistanceFromEnd() < DEFAULT_SCROLL_RENDER_AHEAD` (1000).
3. If it is, it loads another `DEFAULT_PAGE_SIZE` rows of content, then stops.
In the case of the ListView Grid Layout example, this meant that it first loaded 10 cells, then loaded another 1, for a total of 11. The problem was that going from 10 to 11 cells isn't sufficient to fill the visible scroll area, and it doesn't change the `contentSize` (since the cells wrap onto the same line), and since ListView doesn't try to load any more until the `contentSize` or `scrollOffset ` changes, it stops loading new rows at that point.
I tried fixing this by calling `_renderMoreRowsIfNeeded()` after `_pageInNewRows()` so that it will continue to fetch new rows until the `_getDistanceFromEnd()` is less than the threshold, rather than stopping after the first page and waiting until the `contentSize` or `scrollOffset` change, but although this solves the problem for the Grid Layout example, it leads to over-fetching in the more common case of a standard row-based ListView.
In the end, I just increased the `pageSize` to 3 for the Grid Layout example, which makes more sense anyway since loading a page that is not a multiple of the number of cells per row confuses the `_renderMoreRowsIfNeeded` algorithm, and leads to gaps at the bottom of the view.
This solved the problem, however there was still a "pop-in" effect, where the additional rows were paged in after the ListView appeared. This was simply a misconfiguration in the example itself: The default of 10 rows was insufficient to fill the screen, so I changed the `initialListSize` prop to `20`.

Summary: public
RCTUIManager is a public module with several useful methods, however, unlike most such modules, it does not have a JS wrapper that would allow it to be required directly.
Besides making it more cumbersome to use, this also makes it impossible to modify the UIManager API, or smooth over differences between platforms in the JS layer without breaking all of the call sites.
This diff adds a simple JS wrapper file for the UIManager module to make it easier to work with.

Changed ListView to use onLayout and onContentSizeChange (new) events instead of measure. Updated ScrollView implementation to support contentSizeChange event with an implementation based on onLayout attached to the content view. For RecyclerViewBackedScrollView we need to generate that event directly as it doesn't have a concept of content view.
This greatly improves performance of ListView that uses RecyclerViewBackedScrollView
