a8bdb693b9 feat(pipes): add support for pure pipes 
By default, pipes are pure. This means that an instance of a pipe will be reused and the pipe will be called only when its arguments change.

BREAKING CHANGE

Before:

@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.

After:

@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe.
@Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.

8302afffb4 refactor(LifecycleEvent): remove LifecycleEvent 
fixes #3924

BREAKING CHANGE

The `lifecycle` configuration for directive has been dropped.

Before

    // Dart
    @Component({lifecycle: const [LifecycleEvent.OnChanges], ...})
    class MyComponent implements OnChanges {
      void onChanges() {...}
    }

    // Typescript
    @Component({lifecycle: [LifecycleEvent.OnChanges], ...})
    class MyComponent implements OnChanges {
      onChanges(): void {...}
    }

    // ES5
    var MyComponent = ng.
    Component({lifecycle: [LifecycleEvent.OnChanges], ...}).
    Class({
      onChanges: function() {...}
    });

After

    // Dart
    @Component({...})
    class MyComponent implements OnChanges {
      void onChanges() {...}
    }

    // Typescript
    @Component({...})
    class MyComponent implements OnChanges {
      onChanges(): void {...}
    }

    // ES5
    var MyComponent = ng
      .Component({...})
      .Class({
        onChanges: function() {
        }
      });

    this.target = target;

5ebeaf7c9b feat(query): implement query update mechanism based on views. 
Instead of working with finer grained element injectors, queries now
iterate through the views as static units of modification of the
application structure. Views already contain element injectors in the
correct depth-first preorder.

This allows us to remove children linked lists on element injectors and a
lot of book keeping that is already present at the view level.

Queries are recalculated using the afterContentChecked and
afterViewChecked hooks, only during init and after a view container has
changed.

BREAKING CHANGE:
ViewQuery no longer supports the descendants flag. It queries the whole
component view by default.

ea6673947c refactor: rename annotations to metadata 
BREAKING CHANGE (maybe)

Well as long as our customers use public API this should not be a
breaking change, but we have changed import structure as well as
internal names, so it could be breaking.

import:
  angular2/annotations => angular2/metadata

Classes:
  *Annotations => *Metadata
  renderer.DirectiveMetadata => renderer.RendererDirectiveMetadata
  renderer.ElementBinder => renderer.RendererElementBinder
  impl.Directive => impl.DirectiveMetadata
  impl.Component => impl.ComponentMetadata
  impl.View => impl.ViewMetadata

Closes #3660
