BREAKING CHANGE:
Previously, `Directive` was the abstract base class of several directives.
Now, `Directive` is the former `Decorator`, and `Component` inherits from it.
BREAKING_CHANGE:
- The special type of `Viewport` directives is removed
in favor of a more general `Decorator` directive
- `ViewContainerRef` now no more has a default `ProtoViewRef`
but requires an explicit one when creating views.
Closes#1536
BREAKING CHANGES:
- `NgElement` merged into `ElementRef`
- `Compiler.compile…` returns `ProtoViewRef`
- `ViewContainer` uses `ProtoViewRef`s and `ViewRef`s.
- `ViewRef`/`ProtoViewRef` in renderer were renamed to
`RenderViewRef`/`RenderProtoViewRef`.

AppViewManager is the single entry point to changing the view hierarchy.
It is split between the manager itself which does coordination and
helper methods, so both are easily testable in isolation.
Also, ViewContainer is now only a pure reference to a bound element
with the previous functionality but does not contain the list of views
any more.
Part of #1477
Major changes:
- `compiler.compileRoot(el, type)`
-> `compiler.compileInHost(type) + viewHydrator.hydrateHostViewInPlace(el, view)`
- move all `hydrate`/`dehydrate` methods out of `View` and `ViewContainer` into
a standalone class `view_hydrator` as private methods and provide new public
methods dedicated to the individual use cases.
Note: This PR does not change the current functionality, only moves it
into different places.
See design discussion in #1351, in preparation for imperative views.
Introduces angular2/src/core/compiler/ViewFactory which
extracts ProtoView.instantiate and replaces ViewPool.
Note: This is a work in progress commit to unblock other commits.
There will be follow ups to add unit tests, remove TODOs, …
Needed to change Renderer.mergeChildComponentProtoViews to not create
new ProtoViews to be able to deal with cyclic references.
This commit is part of using the new render layer in Angular.
