BREAKING CHANGE: `DifferFactory.create` no longer takes ChangeDetectionRef as a first argument as it was not used and deprecated since v4.

After this, neither @angular/compiler nor @angular/comnpiler-cli depend
on @angular/core.
This add a duplication of some interfaces and enums which is stored
in @angular/compiler/src/core.ts
BREAKING CHANGE:
- `@angular/platform-server` now additionally depends on
`@angular/platform-browser-dynamic` as a peer dependency.

This change allows users to specify multiple exportAs names for a
directive by giving a comma-delimited list inside the string.
The primary motivation for this change is to allow these names to be
changed in a backwards compatible way.
toString() from DefaultIterableDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

Angular can make many assumptions about its event handlers. As a result
the bookkeeping for native addEventListener is significantly cheaper
than Zone's addEventLister which can't make such assumptions.
This change bypasses the Zone's addEventListener if present and always
uses the native addEventHandler. As a result registering event listeners
is about 3 times faster.

In previous version of tsickle abstract class methods were materialized.
The change resulted in 6Kb savings in angular.io bundle.
This change also required the removal of `@private` and `@return` type
annotation as it is explicitly dissalowed by tsickle.
NOTE: removed casts in front of `makeDecorator` due to:

In Node.JS console.log/error/warn functions actually resuls in a socket
write which in turn is considered by Zone.js as an async task.
This means that if there is any exception during change detection in a platform-server
application the error handler will make the Angular Zone unstable which
in turn will cause change detection to run on next tick and cause an
infinite loop.
It is also better to run the error handler outside of the Angular Zone
in general on all platforms so that an error in the error handler itself doesn't cause an
infinite loop.
Fixes#17073, #7774.

Destructuring of the form:
function foo({a, b}: {a?, b?} = {})
breaks strictNullChecks, due to the TypeScript bug https://github.com/microsoft/typescript/issues/10078.
This change eliminates usage of destructuring in function argument lists in cases where it would leak
into the public API .d.ts.
toString() from DefaultKeyValueDiffer is only used in tests and should not
be part of the production code. toString() methods from differs add
~ 0.3KB (min+gzip) to the production bundle size.
This is required as e.g. `token` from `@Inject` is
accessed in string form via makeParamDecorator
but as a property in the `ReflectiveInjector`.
Closes#16889 as this is a more general fix.
This fixes a flicker when transitioning from server rendered page to client rendered page in lazy loaded routes by waiting for the lazy loaded route to finish loading, assuming initialNavigation on the route is set to 'enabled'.

* refactor(core): provide error message in stack for reflective DI
Fixes#16355
* fix(compiler): make AOT work with `noUnusedParameters`
Fixes#15532
* refactor: use view engine also for `NgModuleFactory`s
This is a prerequisite for being able to mock providers
in AOTed code later on.
* docs(animations): fix links to `Component` animations
* docs(core): fix links to `ReflectiveInjector` methods
The `resolve` and other methods were moved from the
`Injector` to the `ReflectiveInjector`.
* docs(core): fix links to `Renderer`
The local links were assuming that that methods were on the
current document (e.g. `RootRenderer`), but they are actually
on the `Renderer` class.
* docs(router): fix links to methods
* docs(forms): fix links to methods
* docs(core): fix links to methods
* docs(router): fix API page links and an internal link
This also clarifies via a test
that we only update projected views when the view is created or destroyed,
but not when it is attached/detached/moved.
Fixes#15578
PR Close#16592
Previously a projected view was only dirty checked when the
component in which it was inserted was dirty checked.
This fix changes the behavior so that a view is also dirty checked if
the declaring component is dirty checked.
Note: This does not change the order of change detection,
only the fact whether a projected view is dirty checked or not.
Fixes#14321
- prevents unsubscribing from the zone on error
- prevents unsubscribing from directive `EventEmitter`s on error
- prevents detaching views in dev mode if there on error
- ensures that `ngOnInit` is only called 1x (also in prod mode)

Angular uses the `ng-version` attribute to indicate which elements
were used to bootstrap an application. However, after 4.0 we also
added this attribute for all dynamically created components.
Fixes#15880
PR Close#16394
When a directive lives on the same element as a component
(e.g. `<my-comp myDir>`), the directive was not able to get hold
of the `ChangeDetectorRef` of the component on that element. However,
as directives are supposed to decorate components, this is incorrect.
This commit enables this use case.
Closes#12816
