Summary:
See https://github.com/facebook/react-native/issues/7680.
On iOS the RCTLocationObserver delegate is overriding `desiredAccuracy` every time CLLocationManager calls `didUpdateLocations` or `didFailWithError`. `desiredAccuracy` is reset to
`RCT_DEFAULT_LOCATION_ACCURACY` (100 meters) This effectively makes it impossible for a react-native app to use any location accuracy other than the default.
This commit simply removes the code which resets the desired accuracy, as there seems to be no rationale for doing so. The reset code was added as part of [a large general
change](705a8e0144) so the original intention is unclear from the history. If somebody can explain it to me, I'm happy to rework this PR accordingly.
Changelog:
----------
[iOS] [Fixed] - Location Services accuracy constantly reset to default of 100 meters.

Summary:
This change enables developers to tell the Geolocation module to skip its permissions requests so the app can manage the permissions requests on its own. React Native Android's Geolocation module already requires apps to request permissions on their own.
Currently, the Geolocation module automatically makes permissions requests for you based on what you've specified in your property list file. However, the property list file doesn't always represent what permissions the app wants right now. For example, suppose an app sometimes wants location when "in use" and sometimes wants location "always" depending on what app features the user has engaged with. The Geolocation API will request the "always" location permission even if that's not what the app wants for the current scenario.
This change enables developers to tell the Geolocation module to skip permission requests so that the app can explicitly ask for the appropriate permissions. By default, Geolocation will still ask for permissions so this is not a breaking change.
This change adds a method to Geolocation that is not supported by the web spec for geolocation (`setRNConfiguration`). This method includes `RN` in the name to minimize the chances that the web spec will introduce an API with the same name.
**Test plan (required)**
Verified that Geolocation requests permissions by default and when `skipPermissionRequests` is `false`. Verified the permission requests are skipped when `skipPermissionRequests` is `true`. Also, my team is using this change in our app.

Summary:
In the yet-to-be-released iOS 11, Apple has changed the way they notify the user of location services. (You can watch their session from WWDC about all the changes [here](https://developer.apple.com/videos/play/wwdc2017/713/).)
The current implementation of `RCTLocationObserver` uses the standard location services from Apple. When the user has granted `Always` location permission and the application uses the background location service, the user is presented with the *_Blue Bar of Shame_* (for more information check out [this blog post](https://blog.set.gl/ios-11-location-permissions-and-avoiding-the-blue-bar-of-shame-1cee6cd93bbe)):
* Added `useSignificantChanges` boolean to the options passed.
* Added `_usingSignificantChanges` boolean based on user options. If `true`, then the CLLocationManager will use functions `startMonitoringSignificantLocationChanges`/ `stopMonitoringSignificantLocationChanges` rather than the standard location services.
* Changed method signature of `beginLocationUpdatesWithDesiredAccuracy` to include `useSignificantChanges` flag
* Added check for new `NSLocationAlwaysAndWhenInUseUsageDescription`
All unit tests passed.
Tested in simulator and on device, toggling `useSignificantChanges` option when calling `watchPosition`. Results were as expected. **When `TRUE`, the _Blue Bar of Shame_ was not present.**
Changes do not affect Android and location services still work as expected on Android.
* Change is for iOS only
* Using a different API will have different accuracy results. Adding `useSignificantChanges` as an option was by design so apps that want to have most accurate and most frequent update can still use standard location services.

My app crashed when I call navigator.geolocation.stopObserving(). I found it is caused by the reason that one argument short. So I added false to the first argument. Then bug is fixed.
1. call both navigator.geolocation.watchPosition and navigator.geolocation.getCurrentPosition
2. then call navigator.geolocation.stopObserving()
3. error happened before I fixed, and correct Warning "Called stopObserving with existing subscriptions." shown after I fixed.

Summary:
Xcode really sucks, per some discussion on e1577df1fd and https://developer.apple.com/library/content/technotes/tn2215/_index.html, if you use the headers phase, and mark headers in your static library as public, they will actually end up in the final package that's built and you can't submit to the app store! This changes our xcode setup to use a copy files phase instead.
I've also changed the header include path to be $(BUILT_PRODUCTS_DIR)/include, which is added to the include path by Xcode by default, so 3rd party libraries should not be impacted by these changes anymore.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".

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:
Allow changing distanceFilter after _locationManager has been initialized.
There is 2 reasons for this PR:
- When calling `getCurrentPosition`, `_observerOptions` is possibly not set properly ( as it is set only in `startObserving`), in this case it would have default values so `distanceFilter` will be 0 in this case ( which can be the right value but we should be more explicit about it, `kCLDistanceFilterNone` or `RCT_DEFAULT_LOCATION_ACCURACY`):

- Another issue is that `distanceFilter` is cached so it can't be changed afterwards:
```javascript
let options;
options = {
enableHighAccuracy: true,
distanceFilter: 20,
};
this.watchId = this.geolocation.watchPosition(
() => { },
() => { },
options,
);
// => sets distanceFilter to 20
this.geolocation.clearWatch(this.watchId);
options = {

Summary:Geolocation timestamp is different for Android and iOs. For Android it is returning in UTC time in milliseconds since January 1, 1970, for iOS it was returned as time interval relative to an absolute reference date (00:00:00 UTC on 1 January 2001). Also for iOS time returned was "current system absolute time" and not the time at which this location was determined.
Tested with 0.21.0-rc React Native. Init project with this additional code:
`constructor(props) {super(props);
navigator.geolocation.getCurrentPosition(

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.

Instantiates the _pendingRequests array before trying to add to it. As it currently stands, we try to add the pending request before the array is created. getCurrentPosition always fails on the first try.

Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand
