Summary:
These got smashed together with some weird rebase snafu. They are pretty intertwined anyway so the value of
separate commits is minimal (e.g. separate commits would not revert cleanly anyway).
== [lists] better fill rate logging (previously D4907958)
After looking through some production data, I think this will address all the issues we're seeing. Now:
- Header/Footer getting no longer counted as blank.
- Avoid floating point for Scuba.
- Compare actual time of blankness, not just samples.
- Include both "any" vs. "mostly" blank (similar to 1 and 4 frame drops).
- Include events where there is no blankness so we have a baseline.
- Remove events with too few samples
**Test Plan: **
A bunch of scrolling in FlatListExample

== [Lists] Update SectionSeparatorItem docs (previously D4909526)
Forgot to update the language here when we modified the behavior with the introduction of separator
highlighting support.
** Test Plan: **
nope.
== [Lists] Add renderSectionFooter prop to SectionList (previously D4923353)
Handy for things like "see more" links and such.
The logic here is to render the footer last, *after* the bottom section separator. This is to preserve
the highlighting behavior of the section separator by keeping it adjacent to the items.
**Test Plan: **
Added to snapshot test and example:
{F66635525}
{F66635526}
== [SectionList] Add a bunch more info for rendering items and separators (previously D4923663)
This extra info can be helpful for rending more complex patterns.
**Test Plan: **
Made snapshot test more comprehensive and inspected the output.
== [Lists] reduce render churn (previously D4924639)
I don't think the velocity based leadFactor is helping and might actually be hurting because
it causes a lot of churn in the items we render.
Instead, this diff introduces fillPreference which biases the window expansion in the direction of scroll,
but doesn't actually affect the final bounds of the window at all, so items that are already rendered are
more likely to stay rendered.
**Test Plan: **
Played around in debug mode and watched the overlay - seems better. Also tests all pass.

== [Lists] Add initialScrollIndex prop
Makes it easy to load a VirtualizedList at a location in the middle of the content without
wasting time rendering initial rows that aren't relevant, for example when opening an infinite calendar
view to "today".
**Test Plan: **
With debug overlay, set `initialScrollIndex={52}` prop in `FlatListExample` and
and see it immediately render a full screen of items with item 52 aligned at the top of the screen. Note
no initial items are mounted per debug overlay. Scroll around a bunch and everything else seems to work
as normal.
No SectionList impl since `getItemLayout` isn't easy to use there.

Summary:
To get on par with iOS this PR adds an `appProperty` to the `ReactRootView`. The documentation on the iOS side is here: [https://facebook.github.io/react-native/docs/communication-ios.html#properties.](https://facebook.github.io/react-native/docs/communication-ios.html#properties.)
You can pass in initial props with the `startReactApplication` method:
```java
…
Bundle initialProps = new Bundle();
bundle.putString(“initialKey”, “initialValue”);
mReactRootView.startReactApplication(mReactInstanceManager, "HelloWorld", initialProps);
setContentView(mReactRootView);
…
```
And later on properties can be updated this way:
```java
…
// Update props
Bundle updatedProps = mReactRootView.getAppProperties();
updatedProps.putString(“someOtherKey”, “someOtherValue”);
mReactRootView.setAppProperties(updatedProps);
// Replace props
Bundle newProps = new Bundle();
newProps.putString(“someKey”, “someValue”);
mReactRootView.setAppProperties(newProps);
…

Summary:
These examples work sporadically, and are all based on a years-old build of UIExplorer that was once uploaded to Appetize. As a result, newer APIs such as FlatList are not supported and attempting to run their associated examples will result in an error.

Summary:
React Native uses JSON to marshal the data across the bridge.
And because of this we have to avoid using NaN and INF values in events and other pieces of data that suppose to be transfered to/from JS side.
(We also don't want to introduce additional wrapping/escaping semantics for perfomance reasons.)
So, we have to gate all particular cases where there is a possibility of NaN or INF values, and replace these value with something meaningful for each particular case.
We are using `0` as NaN substitution here because:
* NaN in touch event is super rare case;
* Conversion to `0` is fast;
* `0` is okay value for product code in most cases;
* In all cases `0` is decent analog to "undefined position on screen" for touch event;
* Nobody will explicitly handle NaN case in product code, just because it is super rare case and actually indicates that something else went wrong.

Apps commonly provide their own rage-shake menus or behaviors, including in dev builds where the dev menu is enabled on shake. Rather than try to override these settings via native code, it can be helpful to let the app define when to show the menu via the bridge.

>The session object keeps a strong reference to the delegate until your app exits or explicitly >invalidates the session. If you do not invalidate the session, your app leaks memory until it exits.
The RCTMultipartDataTask will cause memory leaks, it will make `RCTBatchedBridge` and ` RCTMultipartDataTask` will not release.
So call `[session finishTasksAndInvalidate];` at the end of `startTask` function.

Summary:
The cli arg `--scheme` allows you to override the inferred scheme.
The runOnDevice command takes this override into account, but run-ios
doesn't. This commit fixes this discrepancy.
Thanks for submitting a PR! Please read these instructions carefully:
- [x] Explain the **motivation** for making this change.
- [x] Provide a **test plan** demonstrating that the code is solid.
- [x] Match the **code formatting** of the rest of the codebase.
- [x] Target the `master` branch, NOT a "stable" branch.
Currently if a custom scheme is specified, `run-ios` will fail with the following message
```
Error: Command failed: /usr/libexec/PlistBuddy -c Print:CFBundleIdentifier build/Build/Products/Debug-iphonesimulator/AwesomeProject.app/Info.plist
