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.

Note 4.3 only!
Prior to this fix when [@.disabled] was used in a component that
contained zero animation code it wouldn't register properly because the
renderer associated with that component was not an animation renderer.
This patch ensures that it gets registered even when there are no
animations set.

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 PR fixes an issue where `query(':enter')` will only collect elements up until it an element that is found that isn't apart of the `:enter` query.

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.
`flush()` can now be used from within fakeAsync tests to simulate moving
time forward until all macrotask events have been cleared from the
event queue.
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.
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)
