Add new method `historyGo`, that will let
the user navigate to a specific page from session history identified by its
relative position to the current page.
We add some tests to `location_spec.ts` to validate the behavior of the
`historyGo` and `forward` methods.
Add more tests for `location_spec` to test `location.historyGo(0)`, `location.historyGo()`,
`location.historyGo(100)` and `location.historyGo(-100)`. We also add new tests for
`Integration` spec to validate the navigation when we using
`location#historyGo`.
Update the `historyGo` function docs
Note that this was made an optional function in the abstract classes to
avoid a breaking change. Because our location classes use `implements PlatformLocation`
rather than `extends PlatformLocation`, simply adding a default
implementation was not sufficient to make this a non-breaking change.
While we could fix the classes internal to Angular, this would still have been
a breaking change for any external developers who may have followed our
implementations as an example.

With this change we move `XhrFactory` to the root entrypoint of `@angular/commmon`, this is needed so that we can configure `XhrFactory` DI token at a platform level, and not add a dependency between `@angular/platform-browser` and `@angular/common/http`.
Currently, when using `HttpClientModule` in a child module on the server, `ReferenceError: XMLHttpRequest is not defined` is being thrown because the child module has its own Injector and causes `XhrFactory` provider to be configured to use `BrowserXhr`.
Therefore, we should configure the `XhrFactory` at a platform level similar to other Browser specific providers.
BREAKING CHANGE:
`XhrFactory` has been moved from `@angular/common/http` to `@angular/common`.
**Before**
```ts
import {XhrFactory} from '@angular/common/http';
```
**After**
```ts
import {XhrFactory} from '@angular/common';

The `DomAdapter` is present in all Angular apps and its methods aren't tree shakeable.
These changes remove the methods that either aren't being used anymore or were only
used by our own tests. Note that these changes aren't breaking, because the adapter
is an internal API.
The following methods were removed:
* `getProperty` - only used within our own tests.
* `log` - Guaranteed to be defined on `console`.
* `logGroup` and `logGroupEnd` - Only used in one place. It was in the DomAdapter for built-in null checking.
* `logGroupEnd` - Only used in one place. It was placed in the DomAdapter for built in null checking.
* `performanceNow` - Only used in one place that has to be invoked through the browser console.
* `supportsCookies` - Unused.
* `getCookie` - Unused.
* `getLocation` and `getHistory` - Only used in one place which appears to have access to the DOM
already, because it had direct accesses to `window`. Furthermore, even if this was being used
in a non-browser context already, the `DominoAdapter` was set up to throw an error.
The following APIs were changed to be more compact:
* `supportsDOMEvents` - Changed to a readonly property.
* `remove` - No longer returns the removed node.

In the new behavior Angular cleanups `popstate` and `hashchange` event listeners
when the root view gets destroyed, thus event handlers are not added twice

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.

outlined in the spec by finding a fallback target if the original is not

Even in the overloads, state that it can accept `null` and
`undefined`, in order to ensure easy composition with `async`.
Additionally, change the implementation to return `null` on an
`undefined` input, for consistency with other pipes.
BREAKING CHANGE:
The `slice` pipe now returns `null` for the `undefined` input value,
which is consistent with the behavior of most pipes. If you rely on
`undefined` being the result in that case, you now need to check for it
explicitly.
PR Close#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
way.

anymore.
BREAKING CHANGE:
The async pipe no longer claims to return `undefined` for an input that

The old implementation of case conversion types can handle several
values which are not strings, but the signature did not reflect this.
The new one reports errors when falsy non-string inputs are given to
the pipe (such as `false` or `0`) and has a new signature which
instead reflects the behaviour on `null` and `undefined`.
Fixes#36259
BREAKING CHANGE:
The case conversion pipes no longer let falsy values through. They now
map both `null` and `undefined` to `null` and raise an exception on
invalid input (`0`, `false`, `NaN`) just like most "common pipes". If
your code required falsy values to pass through, you need to handle them
explicitly.

To discourage developers from mutating the arrays returned

as readonly.
* `getLocaleDayPeriods()`

* `getLocaleMonthNames()`
* `getLocaleEraNames()`
Fixes#27003
BREAKING CHANGE:
The locale data API has been marked as returning readonly arrays, rather
than mutable arrays, since these arrays are shared across calls to the
API. If you were mutating them (e.g. calling `sort()`, `push()`, `splice()`, etc)
then your code will not longer compile. If you need to mutate the array, you
should now take a copy (e.g. by calling `slice()`) and mutate the copy.

Currently, the `DatePipe` (via `formatDate()`) rounds fractions of a millisecond to the
nearest millisecond. This can cause dates that are less than a millisecond before midnight
to be incremented to the following day.
The [ECMAScript specification](https://www.ecma-international.org/ecma-262/5.1/#sec-15.9.1.11)
defines that `DateTime` milliseconds should always be rounded down, so that `999.9ms`
becomes `999ms`.
This change brings `formatDate()` and so `DatePipe` inline with the ECMAScript
specification.
Fixes#37989
BREAKING CHANGE:
When passing a date-time formatted string to the `DatePipe` in a format that contains
fractions of a millisecond, the milliseconds will now always be rounded down rather than
to the nearest millisecond.
Most applications will not be affected by this change. If this is not the desired behaviour
then consider pre-processing the string to round the millisecond part before passing
it to the `DatePipe`.

This commit fixes a regression from "fix(common): ensure
scrollRestoration is writable (#30630)" that caused scrolling to not
happen at all in browsers that do not support scroll restoration. The
issue was that `supportScrollRestoration` was updated to return `false`
if a browser did not have a writable `scrollRestoration`. However, the
previous behavior was that the function would return `true` if
`window.scrollTo` was defined. Every scrolling function in the
`ViewportScroller` used `supportScrollRestoration` and, with the update
in bb88c9fa3d, no scrolling would be
performed if a browser did not have writable `scrollRestoration` but
_did_ have `window.scrollTo`.
Note, that this failure was detected in the saucelabs tests. IE does not
support scroll restoration so IE tests were failing.

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.
