Andrew Kushnir a3849611b7 fix(forms): clean up connection between FormControl/FormGroup and corresponding directive instances (#39235)
Prior to this commit, removing `FormControlDirective` and `FormGroupName` directive instances didn't clear
the callbacks previously registered on FromControl/FormGroup class instances. As a result, these callbacks
were executed even after `FormControlDirective` and `FormGroupName` directive instances were destroyed. That was
also causing memory leaks since these callbacks also retained references to DOM elements.

This commit updates the cleanup logic to take care of properly detaching FormControl/FormGroup/FormArray instances
from the view by removing view-specific callback at destroy time.

Closes #20007, #37431, #39590.

George Kalpakas b4b21bdff4 fix(upgrade): fix HMR for hybrid applications (#40045)
Previously, trying to apply a change via Hot Module Replacement (HMR) in
a hybrid app would result in an error. This was caused by not having the
AngularJS app destroyed and thus trying to bootstrap an AngularJS app on
the same element twice.

This commit fixes HMR for hybrid apps by ensuring the AngularJS app is
destroyed when the Angular `PlatformRef` is [destroyed][1] in the
[`module.hot.dispose()` callback][2].

NOTE:
For "ngUpgradeLite" apps (i.e. those using `downgradeModule()`), HMR
will only work if the downgraded module has been bootstrapped and there
is at least one Angular component present on the page. The is due to a
combination of two facts:
- The logic for setting up the listener that destroys the AngularJS app
  depends on the downgraded module's `NgModuleRef`, which is only
  available after the module has been bootstrapped.
- The [HMR dispose logic][3] depends on having an Angular element
  (identified by the auto-geenrated `ng-version` attribute) present in
  the DOM in order to retrieve the Angular `PlatformRef`.

Andrew Scott 112324a614 feat(router): add `relativeTo` as an input to `routerLink` (#39720)
Allow configuration of `relativeTo` in the `routerLink` directive. This
is related to the clearing of auxiliary routes, where you need to use
`relativeTo: route.parent` in order to clear it from the activated
auxiliary component itself. This is because `relativeTo: route` will
consume the segment that we're trying to clear, so there is really no
way to do this with routerLink at the moment.

JiaLiPassion 5e92d649f2 feat(core): add shouldCoalesceRunChangeDetection option to coalesce change detections in the same event loop. (#39422)
Close #39348

Now `NgZone` has an option `shouldCoalesceEventChangeDetection` to coalesce
multiple event handler's change detections to one async change detection.

And there are some cases other than `event handler` have the same issues.
In #39348, the case like this.

```
// This code results in one change detection occurring per
// ngZone.run() call. This is entirely feasible, and can be a serious
// performance issue.
for (let i = 0; i < 100; i++) {
  this.ngZone.run(() => {
    // do something
  });
}
```

So such kind of case will trigger multiple change detections.
And now with Ivy, we have a new `markDirty()` API will schedule
a requestAnimationFrame to trigger change detection and also coalesce
the change detections in the same event loop, `markDirty()` API doesn't
only take care `event handler` but also all other cases `sync/macroTask/..`

So this PR add a new option to coalesce change detections for all cases.

Andrew Kushnir 0723331b2a refactor(forms): move common validators-related logic to the `AbstractControlDirective` class (#38280)
This commit refactors validators-related logic that is common across most of the directives.

A couple notes on this refactoring:
* common logic was moved to the `AbstractControlDirective` class (including `validator` and
`asyncValidator` getters)
* sync/async validators are now composed in `AbstractControlDirective` class eagerly when validators
are set with `_setValidators` and `_setAsyncValidators` calls and the result is stored in directive
instance (thus getters return cached versions of validator fn). This is needed to make sure composed
validator function remains the same (retains its identity) for a given directive instance, so that
this function can be added and later removed from an instance of an AbstractControl-based class
(like `FormControl`). Preserving validator function is required to perform proper cleanup (in followup
PRs) of the AbstractControl-based classes when a directive is destroyed.

Adam c4becca0e4 feat(router): add new initialNavigation options to replace legacy (#37480)
As of Angular v4, four of the options for
`ExtraOptions#initialNavigation` have been deprecated. We intend
to remove them in v11. The final state for these options is:
`enabledBlocking`, `enabledNonBlocking`, and `disabled`. We plan

New options:
- `enabledNonBlocking`: same as legacy_enabled
- `enabledBlocking`: same as enabled

BREAKING CHANGE:

* The `initialNavigation` property for the options in
  `RouterModule.forRoot` no longer supports `legacy_disabled`,
  `legacy_enabled`, `true`, or `false` as valid values.

BREAKING CHANGE:

Directives in the `@angular/forms` package used to have `any[]` as a type of `validators` and

In an unlikely case your code was testing the parnet against undefined with sitrct equality,

Andrea Canciani 4dfe0fa068 fix(common): correct and simplify typing of `KeyValuePipe` (#37447)
As shown in the tests, `KeyValuePipe.transform` can accept
`undefined`, in which case it always returns `null`.

Additionally, the typing for `string` keys can be made generic, so the
comparison function is only required to accept the relevant cases.

Finally, the typing for `number` records now shows that the comparison
function and the result entries will actually receive the string version
of the numeric keys, just as shown in the tests.

BREAKING CHANGE:
The typing of the `keyvalue` pipe has been fixed to report that for
input objects that have `number` keys, the result will contain the
string representation of the keys. This was already the case and the
code has simply been updated to reflect this. Please update the
consumers of the pipe output if they were relying on the incorrect
types. Note that this does not affect use cases where the input values
are `Map`s, so if you need to preserve `number`s, this is an effective

Andrew Scott e0e5c9f195 fix(router): ensure routerLinkActive updates when associated routerLinks change (#38349)
This commit introduces a new subscription in the `routerLinkActive` directive which triggers an update
when any of its associated routerLinks have changes. `RouterLinkActive` not only needs to know when
links are added or removed, but it also needs to know about if a link it already knows about
changes in some way.

Quick note that `from...mergeAll` is used instead of just a simple
`merge` (or `scheduled...mergeAll`) to avoid introducing new rxjs
operators in order to keep bundle size down.

Andrew Scott 71138f6004 feat(compiler-cli): Add compiler option to report errors when assigning to restricted input fields (#38249)
The compiler does not currently report errors when there's an `@Input()`
for a `private`, `protected`, or `readonly` directive/component class member.
This change adds an option to enable reporting errors when a template
attempts to bind to one of these restricted input fields.

Alex Rickabaugh c573d91285 refactor(compiler-cli): allow program strategies to opt out of inlining (#38105)
The template type-checking engine relies on the abstraction interface
`TypeCheckingProgramStrategy` to create updated `ts.Program`s for
template type-checking. The basic API is that the type-checking engine
requests changes to certain files in the program, and the strategy provides
an updated `ts.Program`.

Typically, such changes are made to 'ngtypecheck' shim files, but certain
conditions can cause template type-checking to require "inline" operations,
which change user .ts files instead. The strategy used by 'ngc' (the
`ReusedProgramStrategy`) supports these kinds of updates, but other clients
such as the language service might not always support modifying user files.

To accommodate this, the `TypeCheckingProgramStrategy` interface was
modified to include a `supportsInlineOperations` flag. If an implementation
specifies `false` for inline support, the template type-checking system will
return diagnostics on components which would otherwise require inline
operations.

Andrea Canciani 9c8bc4a239 fix(common): narrow `NgIf` context variables in template type checker (#36627)
When the `NgIf` directive is used in a template, its context variables
can be used to capture the bound value. This is sometimes used in
complex expressions, where the resulting value is captured in a
context variable. There's two syntax forms available:

1. Binding to `NgIfContext.ngIf` using the `as` syntax:
```html
<span *ngIf="enabled && user as u">{{u.name}}</span>
```

2. Binding to `NgIfContext.$implicit` using the `let` syntax:
```html
<span *ngIf="enabled && user; let u">{{u.name}}</span>
```

Because of the semantics of `ngIf`, it is known that the captured
context variable is truthy, however the template type checker
would not consider them as such and still report errors when
`strict` is enabled.

This commit updates `NgIf`'s context guard to make the types of the
context variables truthy, avoiding the issue.

Misko Hevery 2a45b932e2 build: fix broken build (#38274)
```
export const __core_private_testing_placeholder__ = '';
```
This API should be removed. But doing so seems to break `google3` and
so it requires a bit of investigation. A work around is to mark it as
`@codeGenApi` for now and investigate later.
