The Angular LS does not provide quick info when the given position is not
inside a template. As an optimization, we can quickly look at the
file and determine if we are at a position that is part of an Angular
template. If not, we bail before asking the compiler for any more
information. Note that the Angular LS _already_ provides no quick info
when outside a template file, but currently asks the compiler to analyze
the program before it determines that information.

Currently `NgTemplateOutlet` recreates its view if its template is swapped out or a context
object with a different shape is passed in. If an object with the same shape is passed in,
we preserve the old view and we mutate the previous object. This mutation of the original
object can be undesirable if two objects with the same shape are swapped between two
different template outlets.
The current behavior is a result of a limitation in `core` where the `context` of an embedded
view is read-only, however a previous commit made it writeable.
These changes resolve the context mutation issue and clean up a bunch of unnecessary
logic from `NgTemplateOutlet` by taking advantage of the earlier change.
Fixes#24515.

When setting `ngZoneRunCoalescing` to true, `onStable` is not emitted correctly.
the reason is before this commit, the code looks like this:
```
// application code call `ngZone.run()`
ngzone.run(() => {}); // step 1
// inside NgZone, in the OnInvoke hook, NgZone try to delay the checkStable()
function delayChangeDetectionForEvents(zone: NgZonePrivate) {
if (zone.lastRequestAnimationFrameId !== -1) { // step 9
return;
}
zone.lastRequestAnimationFrameId = zone.nativeRequestAnimationFrame.call(global, () => { // step 2
if (!zone.fakeTopEventTask) {
zone.fakeTopEventTask = Zone.root.scheduleEventTask('fakeTopEventTask', () => {
zone.lastRequestAnimationFrameId = -1; // step 3
updateMicroTaskStatus(zone); // step 4
checkStable(zone); // step 6
}, undefined, () => {}, () => {});
}
zone.fakeTopEventTask.invoke();
});
updatemicroTaskStatus(zone);
}
function updateMicroTaskStatus(zone: NgZonePrivate, ignoreCheckRAFId = false) {
if (zone._hasPendingMicrotasks ||
((zone.shouldCoalesceEventChangeDetection || zone.shouldCoalesceRunChangeDetection) &&
zone.lastRequestAnimationFrameId !== -1)) { // step 5
zone.hasPendingMicrotasks = true;
} else {
zone.hasPendingMicrotasks = false;
}
}
function checkStable(zone: NgZonePrivate) {
if (zone._nesting == 0 && !zone.hasPendingMicrotasks && !zone.isStable) { // step 7
try {
zone._nesting++;
zone.onMicrotaskEmpty.emit(null);
...
}
// application ref subscribe onMicroTaskEmpty
ngzone.onMicroTaskEmpty.subscribe(() => {
ngzone.run(() => { // step 8
tick();
});
});
```
and the process is:
1. step 1: application call ngZone.run()
2. step 2: NgZone delay the checkStable() call in a requestAnimationFrame, and also set
zone.lastRequestAnimationFrameId
3. step 3: Inside the requestAnimationFrame callback, reset zone.lastRequestAnimationFrameId first
4. step 4: update microTask status
5, step 5: if zone.lastRequestAnimationFrameId is -1, that means no microTask pending.
6. step 6: checkStable and trigger onMicrotaskEmpty emitter.
7. step 7: ApplicationRef subscribed onMicrotaskEmpty, so it will call another `ngZone.run()` to process
tick()
8. step 8: And this new `ngZone.run()` will try to check `zone.lastRequestAnimationFrameId` in `step 9`
when trying to delay the checkStable(), and since the zone.lastRequestAnimationFrameId is already reset
to -1 in step 3, so this ngZone.run() will run into step 2 again.
9. and become a infinite loop..., so onStable is never emit
in this commit, there is a new flag `zone.isCheckStableRunning` added to
prevent re-entry when `shouldCoaleascing` flag is enabled.

This PR formalizes, documents, and makes public the router outlet contract.
The set of `RouterOutlet` methods used by the `Router` has not changed
in over 4 years, since the introduction of route reuse strategies.
Creation of custom router outlets is already possible and is used by the
Ionic framework
(https://github.com/ionic-team/ionic-framework/blob/master/angular/src/directives/navigation/ion-router-outlet.ts).
There is a small "hack" that is needed to make this work, which is that
outlets must register with `ChildrenOutletContexts`, but it currently
only accepts our `RouterOutlet`.
By exposing the interface the `Router` uses to activate and deactivate
routes through outlets, we allow for developers to more easily and safely
extend the `Router` and have fine-tuned control over navigation and component
activation that fits project requirements.

This is a pre-requisite for #40360. Given the following template which has a listener
that references a variable from a parent template (`name`):
```
<ng-template let-name="name">
<button (click)="hello(name)"></button>
</ng-template>
```
We generate code that looks that looks like. Note how we access `name` through `ctx`:
```js
function template(rf, ctx) {
if (rf & 1) {
const r0 = ɵɵgetCurrentView();
ɵɵelementStart(0, "button", 2);
ɵɵlistener("click", function() {
ɵɵrestoreView(r0);
const name_r0 = ctx.name; // Note the `ctx.name` access here.
const ctx_r1 = ɵɵnextContext();
return ctx_r1.log(name_r0);
});
ɵɵelementEnd();
}
}
```
This works fine at the moment, because the template context object can't be changed after creation.
The changes in #40360 allow for the object to be changed, which means that the `ctx` reference
inside the listener will be out of date, because it was bound during creation mode.
This PR aims to address the issue by accessing the context inside listeners through the saved
view reference. With the new code, the generated code from above will look as follows:
```js
function template(rf, ctx) {
if (rf & 1) {
const r0 = ɵɵgetCurrentView();

In `ViewEncapsulation.Emulated` mode the compiler converts `:host` and
`:host-context` pseudo classes into new CSS selectors.
Previously, when there was both `:host-context` and `:host` classes in a
selector, the compiler was generating incorrect selectors. There are two
scenarios:
* Both classes are on the same element (i.e. not separated). E.g.
`:host-context(.foo):host(.bar)`. This setup should only match the
host element if it has both `foo` and `bar` classes. So the generated
CSS selector should be: `.foo.bar<hostmarker>`.
* The `:host` class is on a descendant of the `:host-context`. E.g.
`:host-context(.foo) :host(.bar)`. This setup should only match the
`.foo` selector if it is a proper ancestor of the host (and not on the
host itself). So the generated CSS selector should be:
`.foo .bar<hostmarker>`.

`@angular/platform-server` provides the foundation for rendering an
Angular app on the server. In order to achieve that, it uses a
server-side DOM implementation (currently [domino][1]).
For rendering on the server to work as closely as possible to running
the app on the browser, we need to make DOM globals (such as `Element`,
`HTMLElement`, etc.), which are normally provided by the browser,
available as globals on the server as well.
Currently, `@angular/platform-server` achieves this by extending the
`global` object with the DOM implementation provided by `domino`. This
assignment happens in the [setDomTypes()][2] function, which is
[called in a `PLATFORM_INITIALIZER`][3]. While this works in most cases,
there are some scenarios where the DOM globals are needed sooner (i.e.
before initializing the platform). See, for example, #24551 and #39950
for more details on such issues.
This commit provides a way to solve this problem by exposing a
side-effect-ful entry-point (`@angular/platform-server/init`), that
shims the `global` object with DOM globals. People will be able to
import this entry-point in their server-rendered apps before
bootstrapping the app (for example, in their `main.server.ts` file).
(See also [#39950 (comment)][4].)
In a future update, the [`universal` schematics][5] will include such an
import by default in newly generated projects.

This commit causes imports added by ngtsc's `ImportManager` to have their
TypeScript "original node" set to the generated `ts.ImportDeclaration`
statement.
In g3, the tsickle transformer runs after the Angular transformer and post-
processes Angular's compilation output. One of its post-processing tasks is
to transform generated imports and references to imported symbols from the
commonjs module system to the g3 module system. Part of this transformation
involves recognizing modules with specific metadata and altering references
to symbols from those modules accordingly.
Normally, tsickle can rely on TypeScript's binding for an imported symbol to
find its origin module and thus the correct metadata for the symbol. However
the Angular transform generates new synthetic imports which don't have such
binding information. Angular's imports are always namespace imports of the
form:
```
import * as qualifier 'module/specifier';
```
References to such an import are then of the form `qualifier.SymbolName`.
To process such imports properly, tsickle needs to be able to associate the
reference to `qualifier` in the expression `qualifer.SymbolName` with the
`ts.ImportDeclaration` statement that defines it. It expects to do this by
looking at the `ts.getOriginalNode()` for the `qualifier` reference, which
should be the `ts.ImportDeclaration`. This commit changes ngtsc's import
generation mechanism to set the original node on `qualifier` identifiers
according to this expectation.
This commit is not tested in the direct compiler tests, since:
1) there is no observable behavior externally from setting the original node
2) we don't have tests that intercept transformer operations (which could be
used to directly assert against the AST nodes)
3) tsickle's published version does not (yet) contain the g3-specific
transformations which rely on the original node and would thus allow the
behavior to be observed.
Instead, we rely on the g3 testing suite to validate the correctness of this
fix. Breaking this functionality would cause g3 compilation errors for
targets, since tsickle would be unable to transform imports correctly.

Currently zone.js patches `setTimeout` and keeps a `tasksByHandleId` map to keep `timerId` <-> `ZoneTask`

is running in the `FakeAsyncZoneSpec` or any other `ZoneSpec` with `onScheduleTask` hooks. The `scheduleTask`
in `timer` patch may not be invoked.
For example:
```
fakeAsync(() => {
setTimeout(() => {});
tick();
});
```
In this case, the `timerId` kept in the `tasksByHandleId` map is not cleared.
This is because the `FakeAsyncZoneSpec` in the `onScheduleTask` hook looks like this.
```
onScheduleTask(delegate, ..., task) {
fakeAsyncScheduler.setTimeout(task);
return task;
}
```
Because `FakeAsyncZoneSpec` handles the task itself and it doesn't call `parentDelegate.onScheduleTask`,
therefore the default `scheduleTask` in the `timer` patch is not invoked.
In this commit, the cleanup logic is moved from `scheduleTask` to `setTimeout` patch entry to
avoid the memory leak.

Two motivations behind this change:
1. We would like to expose the types of the Language Service to external
users (like the VSCode extension) via the npm package, on the top
level of the package
2. We would like the View Engine and Ivy LS to share a common interface
(notably after the inclusion of `getTcb`, the Ivy LS upholds a
strict superset of `ts.LanguageService`; previously both VE and Ivy
LS were aligned on `ts.LanguageService`.)
To this end, this commit refactors the exports on the toplevel of the
`language-service/` package to just be types common to both the VE and
Ivy language services. The VE and Ivy build targets then import and use
these types accordingly, and the expectation is that an external user
will just import the relevant typings from the toplevel package without

that when it parsed date strings that looked like `YYYY-MM` it created a UTC
date that was not affected by the local timezone of the JavaScript engine.
This commit does the same for date strings of the form `YYYY`.
(Note that the previous commit, mentioned above, attempted to fix this case
too but the test was not actually checking the correct input string.)
