Summary:
The `finally` method definition was missing, while it really exists causing a flow error when using it.
Added the method definition and make sure flow doesn't throw any error anymore on a real-life example.

Summary:
Introduces a new mechanism to build source maps that allows us to use real mapping segments instead of just mapping line-by-line.
This mechanism is only used when building development bundles to improve the debugging experience in Chrome.
The new mechanism takes advantage of a new feature in babel-generator that exposes raw mapping objects. These raw mapping objects are converted to arrays with 2, 4, or 5 for the most compact representation possible.
We no longer generate a source map for the bundle that maps each line to itself in conjunction with configuring babel generator to retain lines.
Instead, we create a source map with a large mappings object produced from the mappings of each individual file in conjunction with a “carry over” – the number of preceding lines in the bundle.
The implementation makes a couple of assumptions that hold true for babel transform results, e.g. mappings being in the order of the generated code, and that a block of mappings always belongs to the same source file. In addition, the implementation avoids allocation of objects and strings at all costs. All calculations are purely numeric, and base64 vlq produces numeric ascii character codes. These are written to a preallocated buffer objects, which is turned to a string only at the end of the building process. This implementation is ~5x faster than using the source-map library.
In addition to providing development source maps that work better, we can now also produce individual high-quality source maps for production builds and combine them to an “index source map”. This approach is unfeasable for development source maps, because index source map consistently crash Chrome.
Better production source maps are useful to get precise information about source location and symbol names when symbolicating stack traces from crashes in production.

Summary:
Since API 18, Android locations have had the `isFromMockProvider()` function, to verify the validity of a provided location. This was one of many methods one could verify location data, but as of Marshmallow, the other ways of detecting if "Mock Locations" is on in developer settings has been deprecated or defunct.
This means some devices can only detect location mocking by exposing the method on the location object.
This change provides that exposure.

Summary:
This piece of code can assemble all transitive dependencies of a set of entry modules. It is supposed to replace `ResolutionRequest.getOrderedDependencies`.
It has the following advantages:
- has minimal API surface to other components of the system (uses two functions, exposes one function)
- allows to separate concerns into loading + transforming files, resolving dependencies, gathering all modules belonging to a bundle (this code), and bundling
- allows to specify multiple entry points
- allows to use any kind of dependency ID as entry point (haste IDs, node module IDs, relative paths, absolute paths – depends on the resolver)
- allows to skip files, which allows callers to incrementally update previously retrieved collections of modules

Summary:
This is a follow up of the work by brentvatne in #5052. This addresses the feedback by astreet.
- Uses ReactChoreographer with a new callback type
- Callback dispatch logic moved to JS
- Only calls into JS when needed, when there are pending callbacks, it even removes the Choreographer listener when no JS context listen for idle events.
** Test plan **
Tested by running a background task that burns all remaining idle time (see new UIExplorer example) and made sure that UI and JS fps stayed near 60 on a real device (Nexus 6) with dev mode disabled. Also tried adding a JS driven animation and it stayed smooth.
Tested that native only calls into JS when there are pending idle callbacks.
Also tested that timers are executed before idle callback.
```
requestIdleCallback(() => console.log(1));
setTimeout(() => console.log(2), 100);
burnCPU(1000);
// 2
// 1
```
I did *not* test with webworkers but it should work as I'm using executor tokens.
