Bazel has a restriction that a single output (eg. a compiled version of
//packages/common) can only be produced by a single rule. This precludes
the Angular repo from having multiple rules that build the same code. And
the complexity of having a single rule produce multiple outputs (eg. an
ngc-compiled version of //packages/common and an Ivy-enabled version) is
too high.
Additionally, the Angular repo has lots of existing tests which could be
executed as-is under Ivy. Such testing is very valuable, and it would be
nice to share not only the code, but the dependency graph / build config
as well.
Thus, this change introduces a --define flag 'compile' with three potential
values. When --define=compile=X is set, the entire build system runs in a
particular mode - the behavior of all existing targets is controlled by
the flag. This allows us to reuse our entire build structure for testing
in a variety of different manners. The flag has three possible settings:
* legacy (the default): the traditional View Engine (ngc) build
* local: runs the prototype ngtsc compiler, which does not rely on global
analysis
* jit: runs ngtsc in a mode which executes tsickle, but excludes the
Angular related transforms, which approximates the behavior of plain
tsc. This allows the main packages such as common to be tested with
the JIT compiler.
Additionally, the ivy_ng_module() rule still exists and runs ngc in a mode
where Ivy-compiled output is produced from global analysis information, as
a stopgap while ngtsc is being developed.

This commit adds a new compiler pipeline that isn't dependent on global

The ServiceWorker will redirect navigation requests that don't match any
`asset` or `data` group to the specified index file. The rules for a
request to be classified as a navigation request are as follows:
1. Its `mode` must be `navigation`.
2. It must accept a `text/html` response.
3. Its URL must match certain criteria (see below).
By default, a navigation request can have any URL except for:
1. URLs containing `__`.
2. URLs to files (i.e. containing a file extension in the last path
segment).
While these rules are fine in many cases, sometimes it is desirable to
configure different rules for the URLs of navigation requests (e.g.
ignore specific URLs and pass them through to the server).
This commit adds support for specifying an optional `navigationUrls`
list in `ngsw-config.json`, which contains URLs or simple globs
(currently only recognizing `!`, `*` and `**`).
Only requests whose URLs match any of the positive URLs/patterns and
none of the negative ones (i.e. URLs/patterns starting with `!`) will be
considered navigation requests (and handled accordingly by the SW).
(This is an alternative implementation to #23025.)

Previously, it was necessary to attach on of the three "stability"
jsdoc tags (`@stable`, `@deprecated` or `@experimental`) to each
public API export.
To ensure that the public API was correctly tagged, the `ts-api-guardian`
would check that one of these tags appeared on every public export.
Now the doc-gen is able to compute that a code item is stable if
it does not contain the `@experimental` nor `@deprecated` tags.
Therefore there is no need to provide the `@stable` tag any more; and
this tag has now been marked as deprecated - i.e. it should not be used.

Currently packages like @angular/core ship with the generated metadata

Support for using the `ngModel` input property and `ngModelChange`
event with reactive form directives has been deprecated in
Angular v6 and will be removed in Angular v7.
Now deprecated:
```html
<input [formControl]="control" [(ngModel)]="value">
```
```ts
this.value = 'some value';
```
This has been deprecated for a few reasons. First, developers have
found this pattern confusing. It seems like the actual `ngModel`
directive is being used, but in fact it's an input/output property
named `ngModel` on the reactive form directive that simply approximates
(some of) its behavior. Specifically, it allows getting/setting the
value and intercepting value events. However, some of `ngModel`'s other
features - like delaying updates with`ngModelOptions` or exporting the
directive - simply don't work, which has understandably caused some
confusion.
In addition, this pattern mixes template-driven and reactive forms
strategies, which we generally don't recommend because it doesn't take
advantage of the full benefits of either strategy. Setting the value in
the template violates the template-agnostic principles behind reactive
forms, whereas adding a FormControl/FormGroup layer in the class removes
the convenience of defining forms in the template.
To update your code before v7, you'll want to decide whether to stick
with reactive form directives (and get/set values using reactive forms
patterns) or switch over to template-driven directives.
After (choice 1 - use reactive forms):
```html
<input [formControl]="control">
```
```ts
this.control.setValue('some value');
```
After (choice 2 - use template-driven forms):
```html
<input [(ngModel)]="value">
```
```ts
this.value = 'some value';
```
You can also choose to silence this warning by providing a config for
`ReactiveFormsModule` at import time:
```ts
imports: [
ReactiveFormsModule.withConfig({warnOnNgModelWithFormControl: 'never'});
]
```
Alternatively, you can choose to surface a separate warning for each
instance of this pattern with a config value of `"always"`. This may
help to track down where in the code the pattern is being used as the
code is being updated.
Note: `warnOnNgModelWithFormControl` is set up as deprecated so that it
can be removed in v7 when it is no longer needed. This will not display
properly in API docs yet because dgeni doesn't yet support deprecating
properties in object literals, but we have an open issue to resolve the
discrepancy here: https://github.com/angular/angular/issues/22640.

@Injectable() supports a scope parameter which specifies the target module.
However, it's still difficult to specify that a particular service belongs

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.

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.

Currently a bug exists where attempting to inject SwPush crashes the
application if Service Workers are unsupported. This happens because
SwPush doesn't properly detect that navigator.serviceWorker isn't
set.
This change ensures that all passive observation of SwPush and
SwUpdate doesn't cause crashes, and that calling methods to perform
actions on them results in rejected Promises. It's up to applications
to detect when those services are not available, and refrain from
attempting to use them.
To that end, this change also adds an `isSupported` getter to both
services, so users don't have to rely on feature detection directly
with browser APIs. Currently this simply detects whether the SW API
is present, but in the future it will be expanded to detect whether
a particular browser supports specific APIs (such as push
notifications, for example).
Currently, the way to not use the SW is to not install its module.
However, this means that you can't inject any of its services.
This change adds a ServiceWorkerModule.disabled() MWP, that still
registers all of the right providers but acts as if the browser does
not support Service Workers.
