A long time ago Angular used to support both those attribute notations:
- `*attr='binding'`
- `template=`attr: binding`
Because the last notation has been dropped we can refactor the binding parsing.
Source maps will benefit from that as no `attr:` prefix is added artificialy any
more.

In pipes the content of these tags is now generated automatically.
In directives these tags have been converted to `@usageNotes` tags,

This lets projects like Material change ng_package "bundle index" files to non-conflicting paths
Currently packages like @angular/core ship with the generated metadata
in a path like 'core.js' which overwrites one of the inputs.
Angular material puts the generated file in a path like 'index.js'
Either way these files generated by ng_module rules have the potential
to collide with inputs given by the user, which results in an error.
Instead, give users the freedom to choose a different non-conflicting name.
Also this refactors the ng_package rule, removing the redundant
secondary_entry_points attribute.
Instead, we assume that any ng_module in the deps with a module_name
attribute is a secondary entry point.

We now create npm packages to cover all the public api assertions in tools/public_api_guard.
We no longer depend on ts-api-guardian from npm - it is now stale since the repository was archived.
There is no longer a gulp task to enforce or accept the public API, this is in CircleCI as part of running all bazel test targets.

BREAKING CHANGE: after this change, npm and yarn will issue incompatible peerDependencies warning
We don't expect this to actually break an application, but the application/library package.json

"ng update" supports having multiple packages as part of a group which should be updated together, meaning that e.g. calling "ng update @angular/core" would be equivalent to updating all packages of the group (that are part of the package.json already).
In order to support the grouping feature, the package.json of the version the user is updating to needs to include an "ng-update" key that points to this metadata.
The entire specification for the update workflow can be found here: 2e8b12a4ef/docs/specifications/update.md

This produces a directory following the Angular Package layout spec.
Includes integration test coverage by making a minimal ng_package in integration/bazel.
Unit tests verify the content of the @angular/core and @angular/common packages.
This doesn't totally match our current output, but is good enough to unblock some
early adopters.
It re-uses logic from the rollup_bundle rule in rules_nodejs. It should also
eventually have the .pack and .publish secondary targets like npm_package rule.

Previously, an interceptor attempting to inject HttpClient directly
would receive a circular dependency error, as HttpClient was
constructed via a factory which injected the interceptor instances.
Users want to inject HttpClient into interceptors to make supporting
requests (ex: to retrieve an authentication token). Currently this is
only possible by injecting the Injector and using it to resolve
HttpClient at request time.
Either HttpClient or the user has to deal specially with the circular
dependency. This change moves that responsibility into HttpClient
itself. By utilizing a new class HttpInterceptingHandler which lazily
loads the set of interceptors at request time, it's possible to inject
HttpClient directly into interceptors as construction of HttpClient no
longer requires the interceptor chain to be constructed.

Allows a directive to use the expression passed directly to a property
as a guard instead of filtering the type through a type expression.
This more accurately matches the intent of the ngIf usage of its template
enabling better type inference.
Moved NgIf to using this type of guard instead of a function guard.
Closes: #20967
Closure Compiler cannot infer that the swtich statement is exhaustive,
which causes it to complain that the method does not always return a
value.
Work around the problem by throwing an exception in the default case,
and using the `: never` type to ensure the code is unreachable.
Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.
NgIf was modified to declare an input guard on ngIf.
After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.
For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.
The template compiler will generate code similar to,
```
if (NgIf.ngIfTypeGuard(instance.person)) {
instance.person.name
}
```
to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

This changes XhrBackend to not strip the XSSI prefix from error text
if such a prefix is present but the remaining body does not parse as
JSON.
PR Close#19958
Previously, XhrBackend would call JSON.parse('') if the response body was
empty (a 200 status code with content-length 0). This changes the XhrBackend
to attempt the JSON parse only if the response body is non-empty. Otherwise,
the body is left as null.

Previously, HttpClient used the overly clever test "body || null"
to determine when a body parameter was provided. This breaks when
the valid bodies '0' or 'false' are provided.
This change tests directly against 'undefined' to detect the presence
of the body parameter, and thus correctly allows falsy values through.
