This adds the feature for `@ViewChild`/`@ViewChildren`/`@ContentChild`/`@ContentChildren` to define what to read from the queried element.
E.g. `@ViewChild(`someVar`, read: ViewContainerRef)` will locate the element with a variable `someVar` on it and return a `ViewContainerRef` for it.
Background: With this change, Angular knows exactly at which elements there will be `ViewConainerRef`s as the user has to ask explicitly of them. This simplifies codegen and will make converting Angular templates into server side templates simpler as well.
BREAKING CHANGE:
- `DynamicComponentLoader.loadIntoLocation` has been removed. Use `@ViewChild(‘myVar’, read: ViewContainerRef)` to get hold of a `ViewContainerRef` at an element with variable `myVar`.
- `DynamicComponentLoader.loadNextToLocation` now takes a `ViewContainerRef` instead of an `ElementRef`.
- `AppViewManager` is renamed into `ViewUtils` and is a mere private utility service.
Each compile template now exposes a `<CompName>NgFactory` variable
with an instance of a `ComponentFactory`.
Calling `ComponentFactory.create` returns a `ComponentRef` that can
be used directly.
BREAKING CHANGE:
- `Compiler` is renamed to `ComponentResolver`,
`Compiler.compileInHost` has been renamed to `ComponentResolver.resolveComponent`.
- `ComponentRef.dispose` is renamed to `ComponentRef.destroy`
- `ViewContainerRef.createHostView` is renamed to `ViewContainerRef.createComponent`
- `ComponentFixture_` has been removed, the class `ComponentFixture`
can now be created directly as it is no more using private APIs.

BREAKING CHANGE:
`Location` and other related providers have been moved out of `router` and into `platform/common`. `BrowserPlatformLocation` is not meant to be used directly however advanced configurations may use it via the following import change.
Before:
```
import {
PlatformLocation,
Location,
LocationStrategy,
HashLocationStrategy,
PathLocationStrategy,
APP_BASE_HREF}
from 'angular2/router';
import {BrowserPlatformLocation} from 'angular2/src/router/location/browser_platform_location';
```
After:
```
import {
PlatformLocation,
Location,
LocationStrategy,
HashLocationStrategy,
PathLocationStrategy,
APP_BASE_HREF}
from 'angular2/platform/common';
import {BrowserPlatformLocation} from 'angular2/src/platform/browser/location/browser_platform_location';
```
Closes#7962
BREAKING CHANGE:
- Renderer:
* renderComponent method is removed form `Renderer`, only present on `RootRenderer`
* Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
now take the DebugInfo directly.
- Query semantics:
* Queries don't work with dynamically loaded components.
* e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
* 1. dirty check component inputs
* 2. dirty check content children
* 3. update render nodes

BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
BREAKING CHANGE:
In Dart we used to support injecting types with generics. As this feature is hard to implement with the upcoming codegen we are dropping it.
Merge cl/115454020 in G3 with this change.

Now, using `ng.probe(element)` in the browser console returns
a DebugElement when in dev mode.
`ComponentFixture#debugElement` also returns a new DebugElement.
Breaking Change:
This is a breaking change for unit tests. The API for the DebugElement
has changed. Now, there is a DebugElement or DebugNode for every node
in the DOM, not only nodes with an ElementRef. `componentViewChildren` is
removed, and `childNodes` is a list of ElementNodes corresponding to every
child in the DOM. `query` no longer takes a scope parameter, since
the entire rendered DOM is included in the `childNodes`.
Before:
```
componentFixture.debugElement.componentViewChildren[0];
```
After
```
// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];
```
Before:
```
debugElement.query(By.css('div'), Scope.all());
```
After:
```
debugElement.query(By.css('div'));
```
Before:
```
componentFixture.debugElement.elementRef;
```
After:
```
componentFixture.elementRef;
```

BREAKING CHANGE: remove TemplateRef.elementRef setter

BREAKING CHANGE:
- Platform pipes can only contain types and arrays of types,
but no bindings any more.
- When using transformers, platform pipes need to be specified explicitly
in the pubspec.yaml via the new config option
`platform_pipes`.
- `Compiler.compileInHost` now returns a `HostViewFactoryRef`
- Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
instead of `RenderElementRef`s or `RenderViewRef`s
Closes#5993

Previously Angular would run in dev prod mode by default, and you could enable the dev mode by calling enableDevMode.
After
Now, Angular runs in the dev mode by default, and you can enable the prod mode by calling enableProdMode.
Since AppRootUrl is removed, the logic for extending and emitting
the root url as part of the setup seems unnecessary.
BREAKING CHANGES:
The setupWebWorker function exported from
angular2/platform/worker_app no longer returns a promise of providers,
but instead synchronously returns providers.

This changes the public api spec to check each public barrel individually
to make sure its API has not changed. The previous API spec has been
preserved but split into respective barrels.
The compiler barrel has been added to the spec, along with all of its
public exports. Previously, angular2/angular2 was only exporting a
handful of symbols from compiler, so there are now many more symbols
being tested in the spec for compiler than previously.

BREAKING CHANGE:
toPromise is no longer an instance method of the `Observable` returned
by Angular, and fromPromise is no longer available as a static method.
The easiest way to account for this change in applications is to import
the auto-patching modules from rxjs, which will automatically add these
operators back to the Observable prototype.
```
import 'rxjs/add/operator/toPromise';
import 'rxjs/add/observable/fromPromise';
```

BREAKING CHANGE:
RxJS imports now are via `rxjs` instead of `@reactivex/rxjs`
Individual operators can be imported `import 'rxjs/operators/map'`
BREAKING CHANGE:
Previously, pipes that wanted to be notified when they were destroyed
would implement the PipeOnDestroy interface and name the callback
`onDestroy`. This change removes the PipeOnDestroy interface and
instead uses Angular's lifecycle interface `OnDestroy`, with the
`ngOnDestroy` method.
Before:
```
import {Pipe, PipeOnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
onDestroy() {}
}
```
After:
import {Pipe, OnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
ngOnDestroy() {}
}
BREAKING CHANGE:
Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.
To fix, just rename these methods:
* onInit
* onDestroy
* doCheck
* onChanges
* afterContentInit
* afterContentChecked
* afterViewInit
* afterViewChecked
* _Router Hooks_
* onActivate
* onReuse
* onDeactivate
* canReuse
* canDeactivate
To:
* ngOnInit,
* ngOnDestroy,
* ngDoCheck,
* ngOnChanges,
* ngAfterContentInit,
* ngAfterContentChecked,
* ngAfterViewInit,
* ngAfterViewChecked
* _Router Hooks_
* routerOnActivate
* routerOnReuse
* routerOnDeactivate
* routerCanReuse
* routerCanDeactivate
The names of lifecycle interfaces and enums have not changed, though interfaces
have been updated to reflect the new method names.
