Instantiating the test component within an NgZone will let us track async tasks in event handlers and change detection.
We can also do auto change detection when triggering events through dispatchEvent and not have to do fixture.detectChange() manually in the test.
New API:
ComponentFixture.autoDetectChanges() - This puts the fixture in auto detect mode that automatically calls detectChanges when the microtask queue is empty (Similar to how change detection is triggered in an actual application).
ComponentFixture.isStable() - This returns a boolean whether the fixture is currently stable or has some async tasks that need to be completed.
ComponentFixture.whenStable() - This returns a promise that is resolved when the fixture is stable after all async tasks are complete.

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

Useful for avoiding doing an actual XHR during testing.
Part of the solution for #4051 (Other part is a Karma plugin that will create the template cache).
Closes#7940
@petebacondarwin deserves credit for most of this commit.
This allows you to specify a regex and serializer function instead
of the path DSL in your route declaration.
```
@RouteConfig([
{ regex: '[a-z]+.[0-9]+',
serializer: (params) => `{params.a}.params.b}`,
component: MyComponent }
])
class Component {}
```
Closes#7325Closes#7126
With providers split into bundles, the test injector is now able to
use providers for a given bundle. Suggested provider lists for tests are
available in `angular2/platform/testing/<platform>`.
Change the providers for a test suite using `setBaseTestProviders`. This
should be done once at the start of the test suite, before any test cases
run.
BREAKING CHANGE: Tests are now required to use `setBaseTestProviders`
to set up. Assuming your tests are run on a browser, setup would change
as follows.
Before:
```js
// Somewhere in test setup
import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
BrowserDomAdapter.makeCurrent
```
After:
```js
// Somewhere in the test setup
import {setBaseTestProviders} from 'angular2/testing';
import {
TEST_BROWSER_PLATFORM_PROVIDERS,
TEST_BROWSER_APPLICATION_PROVIDERS
} from 'angular2/platform/testing/browser';
setBaseTestProviders(TEST_BROWSER_PLATFORM_PROVIDERS,
TEST_BROWSER_APPLICATION_PROVIDERS);
```
