Summary:
This just moves the jni code that actual figures out the cache dir into OnLoad.cpp and then passes it down to the JSCEXecutorFactory.

Chris Hopman 75ca46e332 Inject some behavior from react/jni/ to react/
Summary:
So, this makes it so a set of behaviors that require accessing java can be injected from the jni/ folder. The behaviors are logging, perf logging, log markers and loading script from assets.

I'd argue that these should all actually be encapsulated by interfaces that are passed to the JSCExecutor/others (and I'd say that's regardless of whether they are injected from jni/ or not), but I wanted to stick to the least disruptive pattern for these changes.

Christopher Dro 109036b4c4 Expose option for distance filtering on location updates.
Summary:
My original implementation involved creating a `RCT_ENUM_CONVERTER` with `CLLocationAccuracy` on iOS and a Hashmap on Android that would convert `string` values to `doubles` for distance filtering.

I got this to work just fine but realized that I made things more complicated than they needed to be and simplified everything by just have the option be a decimal value (in meters) that works both for iOS and Android.

The only thing i'm not sure about is if we can set arbitrary values for CLLocationManager's distance filter.

Alex Kotliarskyi 64d56f34b7 Improve Chrome debugger
Summary:
`debugger.html` contained a ton of hacky code that was needed to ensure we have a clean JS runtime every time a client RN app connects. That was needed because we used the page's global environment as runtime. Some time ago WebWorker support was added and now we run RN code inside an isolated WebWorker instance, and we can safely get rid of all these hacks.

This has a bunch of nice side-effects: debug reload works faster, `console.log`s are preserved, `debuggerWorker.js` selection doesn't change.

Made sure the debugging (breakpoints, etc.) still works as before.

Adam Miskiewicz 6ac007b2ba Use new DisplayMetrics object in `getDisplayMetrics` as to not overwrite Android global state
Summary:
The change in 8e603940e3 actually causes a super bad bug when `context.getResources().getDisplayMetrics()` is accessed in other parts of the application.

It turns out that when you dive into the impl of `getRealMetrics`, it mutates whatever `DisplayMetrics` object is passed to it. In this case, `getDisplayMetrics` ends up mutating the `DisplayMetrics` object that sits on the application context's `Resources` instance.

This PR makes that not so.

Nick Lockwood 81fb985335 Support non-image assets in packager
Summary:
public
The packager currently assumes that all assets that are not JSON or JS files must be images. Although it is possible to add other extension types, they crash the packager if you try to require them, because it attempts to get their dimensions, assuming that they are an image.

This is a crude workaround for that problem, which skips the image-specific processing for non-image assets, but really it would be better if the packager was properly aware of different asset types and treated them differently (e.g. for sounds it could include the duration, for HTML pages it could parse and include linked CSS files, etc).

I've also added an example of using `require('...')` to load a packager-managed HTML page in the UIExplorer WebView example. In future I anticipate that all static asset types (sounds, fonts, etc.) could be handled in this way, which allows them to be edited or added/removed on the fly instead of needing to restart the app.

Janic Duplessis db74e713fe Fix scrollTo when using RefreshControl on Android
Summary:
The issue is that the ScrollResponder mixin assumes that the native scrollable node is the top level element and gets it using `React.findNodeHandle(this)` but since Android wraps the native `ScrollView` component with the `RefreshControl`, it finds the native `RefreshControl` node instead and the scroll command gets ignored because it doesn't exists.

This adds a hook to ScrollResponder mixin to allow specifying what is the native scrollable node.

The bug can be reproduced using this https://gist.github.com/janicduplessis/871c0b6d3ad0acaacba9 in UIExplorer.

Adam Miskiewicz e6cb02d61a Use "babel-preset-react-native"
Summary:
Rather than specifying Babel plugins in the `.babelrc` packaged with react-native, leverage a Babel preset to define the plugins (https://github.com/exponentjs/babel-preset-react-native).

This allows for a much better user experience for those who want (or need) to override options in their project's `.babelrc`.

Prior to this PR, if a user wanted to use a custom babel-plugin (or a custom set of babel plugins), they'd have either 1) manually override the `.babelrc` in the react-packager directory (or fork RN), or 2) specify a custom transformer to use when running the packager that loaded their own `.babelrc`. Note - the custom transformer was necessary because without it, RN's `.babelrc` options would supersede the options defined in the project's `.babelrc`...potentially causing issues with plugin ordering.

This PR makes the transformer check for the existence of a project-level `.babelrc`, and if it it's there, it _doesn't_ use the react-native `.babelrc`. This prevents any oddities with Babel plug

You can repro the bug using this example in UIExplorer by doing a pull to refresh and scrolling the ListView immediately after.

Janic Duplessis b979128c54 Cross platform status bar API
Summary:
I started working on improving the `StatusBar` API and make it work on Android. I added support for `setColor`, `setTranslucent` (the status bar is still visible but the app can draw under) and `setHidden` on Android. Looking for feedback on how to improve the API before I put more time on this :).

Right now I went for a cross platform API and functions that don't exist on a platform are just a no-op but I'm not sure it is the best choice since at the moment what is supported is very different between both platforms. I was wondering what you guys think and if it would be better off as 2 different modules.

It is also possible to port some of the features I added for Android to iOS even if there is no 'standard' way to do it. Like `setColor` could be implemented by drawing a colored view under the status bar and translucent by adding/removing some padding.

Summary:

This adds support to set the highlight color on TextInput on Android.  See https://github.com/facebook/react-native/pull/5678 for the iOS implementation.

Note : We will merge these two properties with one name 'selectionColor' in a follow on diff, and may move it to a style.

Martin Kralik 2e8eb652e1 coalesce "touchMove" events (7/7)
Summary:
This is a final diff in the stack, which makes us not send a bazillion events to js after it's been busy while an user dragged his finger on a screen (resulting in ~two events per frame).
I made "touchMove" event to be coalescable, which makes us not send anything while dragging (since this makes both scroll events and touch move events coalesced and not being  send until either next js frame or the next different touch event occurs).

This change is far from perfect. The event name is a hard coded string and the coalescing works with some (reasonable) assumptions on internal structure of these touch events. Which may or may not be really true. It would be great if someone could comment on these.
I'm thinking about making the touches more strongly typed. Any thoughts on this?

Martin Kralik 4aaa35a22e use RCTEventDispatcher for touch events (6/7)
Summary:
This diff finally makes touch events to be emitted to js from the same object as scroll events. Thanks to changes in previous diffs this means the js will now process them in the right order.

This diff on its own would cause us to send events to js on every frame while dragging a finger on the screen. This is something we tried to avoid with event coalescing in the past, and gets fixed in the following diff D2884595.

**This diff is part of a larger stack. This is a high level overview about what’s going on here.**

This stack of diffs fixes an issue where scroll events and touch events wouldn’t be processed in the correct order on js side.
Current state of world:
* touch events are send to js immediately when they happen (this makes js respond to touches as soon as possible)
* scroll events are buffered, coalesced and send at the beginning of each js frame (coalescing helps in a case where js is busy processing for several native frames and would get all scroll event for that period afterwards)

How did I change this?
1. I’ve made touch events go through the same class every other event (scroll events included) go, RCTEventDispatcher. This gives us a single place to handle all events.
2. I’ve changed RCTEventDispatcher to flush all buffered events every time it gets a touch event before dispatching the touch. This fixes the original ordering issue.
3. I’ve made “touchMove” behave the same way as scroll events do - they are buffered and coalesced. Since “touchMove” events are fired as often as scroll events (while you drag your finger around), doing only 2. would bring back the issue buffering was fixing.
All of this together effectively still keeps the order of events right, avoids overloading js in the important case we care about. The only downside is an increased latency for “touchMove” events, since they are to longer send to js immediately.

(Even better solution would be changing the native->js event passing system to be pull based instead of push based. That way js would always request touches that has happened since the last time it has asked, which would make it get them as soon as it’s possible to process them and native could do coalescing at that point.
However this change has a much bigger scope, so I’m going with this stack of diffs for now.)

Summary:
This diff adds an implementation of `RCTEvent` protocol which represents touch events.
It's basically a copy of this code: c14cc123d5/React/Base/RCTTouchHandler.m (L194-L196)
which is replaced using `RCTTouchEvent` in the next diff (D2884593).
