Let's say we have a code like
```html
<div<span>123</span>
```
Currently this gets parsed into a tree with the element tag `div<span`.
This has at least two downsides:
- An incorrect diagnostic that `</span>` doesn't close an element is
emitted.
- A consumer of the parse tree using it for editor services is unable to
provide correct completions for the opening `<span>` tag.
This patch attempts to fix both issues by instead parsing the code into
the same tree that would be parsed for `<div></div><span>123</span>`.
In particular, we do this by optimistically scanning an open tag as
usual, but if we do not notice a terminating '>', we mark the tag as
"incomplete". A parser then emits an error for the incomplete tag and
adds a synthetic (recovered) element node to the tree with the
incomplete open tag's name.
What's the downside of this? For one, a breaking change.
<ol>
<li>
The first breaking change is that `<` symbols that are ambiguously text
or opening tags will be parsed as opening tags instead of text in
element bodies. Take the code
```html
<p>a<b</p>
```
Clearly we cannot have the best of both worlds, and this patch chooses
to swap the parsing strategy to support the new feature. Of course, `<`
can still be inserted as text via the `<` entity.

This commit re-enables some tests that were temporarily disabled on Windows,
as they failed on native Windows CI. The Windows filesystem emulation has
been corrected in an earlier commit, such that the original failure would
now also occur during emulation on Linux CI.
PR Close#37782
In native windows, the drive letter is a capital letter, while our Windows
filesystem emulation would use lowercase drive letters. This difference may
introduce tests to behave differently in native Windows versus emulated
Windows, potentially causing unexpected CI failures on Windows CI after a PR
has been merged.

NG_VALUE_ACCESSOR is a multi injection token, users can and
should expect more than one ControlValueAccessor to be
available (and this is how it is used in @angular/forms).
This is now reflected in the definition of the injection token
by typing it as an array of ControlValueAccessor. The motivating
reason is that using the programmatic Injector api will now
type Injector#get correspondingly.
fixes#29351
BREAKING CHANGES
NG_VALUE_ACCESSOR is now typed as a readonly array rather than
a mutable scalar. It is used as a multi injection token and as
such it should always be expected that more than one accessor
may be returned.

in the XMLHttpRequest patch, when get `readystatechange` event, zone.js try to
invoke `load` event listener first, then call `invokeTask` to finish the
`XMLHttpRequest::send` macroTask, but if the request failed because the
server can not be reached, the `load` event listener will not be invoked,
so the `invokeTask` of the `XMLHttpRequest::send` will not be triggered either,
so we will have a non finished macroTask there which will make the Zone
not stable, also memory leak.
So in this PR, if the `XMLHttpRequest.status = 0` when we get the `readystatechange`
event, that means something wents wrong before we reached the server, we need to
invoke the task to finish the macroTask.

In #38666 we changed how ngcc deals with type expressions, where it
would now always emit the original type expression into the generated
code as a "local" type value reference instead of synthesizing new
imports using an "imported" type value reference. This was done as a fix
to properly deal with renamed symbols, however it turns out that the
compiler has special handling for certain imported symbols, e.g.
`ChangeDetectorRef` from `@angular/core`. The "local" type value
reference prevented this special logic from being hit, resulting in
incorrect compilation of pipe factories.
This commit fixes the issue by manually inspecting the import of the
type expression, in order to return an "imported" type value reference.
By manually inspecting the import we continue to handle renamed symbols.

Common AST formats such as TS and Babel do not use a separate
node for comments, but instead attach comments to other AST nodes.
Previously this was worked around in TS by creating a `NotEmittedStatement`
AST node to attach the comment to. But Babel does not have this facility,
so it will not be a viable approach for the linker.
This commit refactors the output AST, to remove the `CommentStmt` and
`JSDocCommentStmt` nodes. Instead statements have a collection of
`leadingComments` that are rendered/attached to the final AST nodes
when being translated or printed.

zone.js 0.11.1 introduces a breaking change to adpat Angular package format,
and it breaks the module loading order, before 0.11, in IE11, the `zone.js` es5
format bundle will be imported, but after 0.11, the `fesm2015` format bundle will
be imported, which causes error.
And since the only purpose of the `dist` folder of zone.js bundles is to keep backward
compatibility, in the original commit, I use package redirect to implement that, but
it is not fully backward compatible, we should keep the same dist structure as `0.10.3`.

Before Zone.js `v0.11.1`, Zone.js provides two format of bundles under `dist` folder,
`ES5` bundle `zone.js` and `ES2015` bundle `zone-evergreen.js`, these bundles are used
for `differential loading` of Angular. By default, the following code
```
import 'zone.js';
```
loads the `ES5` bundle `zone.js`.
From `v0.11.1`, Zone.js follows the [Angular Package Format]
(https://docs.google.com/document/d/1CZC2rcpxffTDfRDs6p1cfbmKNLA6x5O-NtkJglDaBVs),
so the folder structure of the Zone.js bundles is updated to match `Angular Package Format`.
So the same code
```
import 'zone.js';
```
loads the `ES2015` bundle.
This is a breaking change, so if the apps import zone.js in this way,
the apps will not work in legacy browsers such as `IE11`.
Zone.js still provides the same bundles under `dist` folder to keep backward
compatibility after `v0.11.1`. So the following code in `polyfills.ts` generated
by `Angular CLI` still works.
```
import 'zone.js/dist/zone';
```

In #38227 the signatures of `navigateByUrl` and `createUrlTree` were updated to exclude unsupported
properties from their `extras` parameter. This migration looks for the relevant method calls that
pass in an `extras` parameter and drops the unsupported properties.
**Before:**
```
this._router.navigateByUrl('/', {skipLocationChange: false, fragment: 'foo'});
```
**After:**
```
this._router.navigateByUrl('/', {
/* Removed unsupported properties by Angular migration: fragment. */
skipLocationChange: false
});
```
These changes also move the method call detection logic out of the `Renderer2` migration and into
a common place so that it can be reused in other migrations.

The `createOrReuseChildren` function calls shouldReuseRoute with the
previous child values use as the future and the future child value used
as the current argument. This is incosistent with the argument order in
`createNode`. This inconsistent order can make it difficult/impossible
to correctly implement the `shouldReuseRoute` function. Usually this
order doesn't matter because simple equality checks are made on the
args and it doesn't matter which is which.
More detail can be found in the bug report: #16192.
Fix#16192
BREAKING CHANGE: This change corrects the argument order when calling
RouteReuseStrategy#shouldReuseRoute. Previously, when evaluating child
routes, they would be called with the future and current arguments would
be swapped. If your RouteReuseStrategy relies specifically on only the future
or current snapshot state, you may need to update the shouldReuseRoute
implementation's use of "future" and "current" ActivateRouteSnapshots.
