Queries allow a directive to inject a live list of directives of a given
type from its LightDom. The injected list is Iterable (in JS and Dart).
It will be Observable when Observables are support in JS, for now it
maintains a simple list of onChange callbacks API.
To support queries, element injectors now maintain a list of
child injectors in the correct DOM order (dynamically updated by
viewports).
For performance reasons we allow only 3 active queries in an injector
subtree. The feature adds no overhead to the application when not
used. Queries walk the injector tree only during dynamic view
addition/removal as triggered by viewport directives.
Syncs changes between viewContainer on the render and logic sides.
Closes#792
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.
Based on the discussion in #776 we can't reliably check if a given
element has a particular property at the compilation time. As such
the existing algorithm detecting "missing" directives can't be used.
We need to see if there is a different / better algorithm or maybe
those checks need to be moved later in the process (runtime). Leaving
integration tests in place (disabled) so we can come back to the
topic after unblocking the situation.

fixes#614
Asynchronous test should inject an AsyncTestCompleter:
Before:
it("async test", (done) => {
// ...
done();
});
After:
it("async test", inject([AsyncTestCompleter], (async) => {
// ...
async.done();
}));
Note: inject() is currently a function and the first parameter is the
array of DI tokens to inject as the test function parameters. This
construct is linked to Traceur limitations. The planned syntax is:
it("async test", @Inject (async: AsyncTestCompleter) => {
// ...
async.done();
});
