Commit 0df719a46 introduced registration of NgModules with ids when compiled
with AOT, and f74373f2d corrected the timing to avoid issues with tree
shaking. Neither of these approaches were correct.
This commit fixes the timing to match View Engine and avoid tree shaking
issues, as well as fixes a bug with the registration of imported module ids.
A new Ivy-only test is added which verifies that modules get registered
correctly under real-world conditions.

Prior to this commit there were no explicit types setup for NgModuleFactory calls in ngfactories, so TypeScript inferred the type based on a given call. In some cases (when generic types were used for Components/Directives) that turned out to be problematic, so we add explicit typing for NgModuleFactory calls.

Plural ICU expressions depend on the locale (different languages have different plural forms). Until now the locale was hard coded as `en-US`.
For compatibility reasons, if you use ivy with AOT and bootstrap your app with `bootstrapModule` then the `LOCALE_ID` token will be set automatically for ivy, which is then used to get the correct plural form.
If you use JIT, you need to define the `LOCALE_ID` provider on the module that you bootstrap.
For `TestBed` you can use either `configureTestingModule` or `overrideProvider` to define that provider.
If you don't use the compat mode and start your app with `renderComponent` you need to call `ɵsetLocaleId` manually to define the `LOCALE_ID` before bootstrap. We expect this to change once we start adding the new i18n APIs, so don't rely on this function (there's a reason why it's a private export).

The removal of @angular/http is now mentioned under breaking changes.
This removes several duplicate entries from the changelog and removes
long and incorrect "closes" links to sources on Github. Those links were
present in the commit message and are incorrectly seen as issue references.
Additionally, code references are wrapped in backticks for proper formatting.

"You need to do nothing" indicates the presence of an action (the action of doing nothing) while the goal is to tell the user that no action is required from them. I think "You don’t need to do anything" is better suitable in this context.

This patch is one of the final patches to refactor the styling algorithm
to be more efficient, performant and less complex.
This patch enables sanitization support for map-based and prop-based
style bindings.

Instead of linking to a markdown file explaining what the migration warnings
are about, we should link to the deprecation guide which now also contains
an entry for that schematic. This makes the deprecation explanations
consistent and more centralized.

With this change we reduce the amount of IO operations. This is especially a huge factor in windows since IO ops are slower.
With this change mainly we cache `existsSync` and `readFileSync` calls

This fixes a collision between #30639 and #30543 where the latter added
usages of @ViewChild without the static flag present, but the former
made the flag required.
PR Close#30666
This commit makes the static flag on @ViewChild and @ContentChild required.
BREAKING CHANGE:
In Angular version 8, it's required that all @ViewChild and @ContentChild
queries have a 'static' flag specifying whether the query is 'static' or
'dynamic'. The compiler previously sorted queries automatically, but in
8.0 developers are required to explicitly specify which behavior is wanted.
This is a temporary requirement as part of a migration; see
https://angular.io/guide/static-query-migration for more details.
@ViewChildren and @ContentChildren queries are always dynamic, and so are
unaffected.

This patch in the second runtime change which refactors how styling
bindings work in Angular. This patch refactors how map-based
`[style]` and `[class]` bindings work using a new algorithm which
is faster and less complex than the former one.
This patch is a follow-up to an earlier refactor which enabled
support for prop-based `[style.name]` and `[class.name]`
bindings (see f03475cac8).

This is a new feature of the Ivy TestBed.
A common user pattern is to test one component with another. This is
commonly done by creating a `TestFixture` component which exercises the
main component under test.
This pattern is more difficult if the component under test is declared in an
NgModule but not exported. In this case, overriding the module is necessary.
In g3 (and View Engine), it's possible to use an NgSummary to override the
recompilation of a component, and depend on its AOT compiled factory. The
way this is implemented, however, specifying a summary for a module
effectively overrides much of the TestBed's other behavior. For example, the
following is legal:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
aotSummaries: [FooModuleNgSummary],
});
```
Here, `FooCmp` is declared in both the testing module and in the imported
`FooModule`. However, because the summary is provided, `FooCmp` is not
compiled within the context of the testing module, but _is_ made available
for `TestFixture` to use, even if it wasn't originally exported from
`FooModule`.
This pattern breaks in Ivy - because summaries are a no-op, this amounts
to a true double declaration of `FooCmp` which raises an error.
Fixing this in user code is possible, but is difficult to do in an
automated or backwards compatible way. An alternative solution is
implemented in this PR.
This PR attempts to capture the user intent of the following previously
unsupported configuration:
```typescript
TestBed.configureTestingModule({
declarations: [FooCmp, TestFixture],
imports: [FooModule],
});
```
Note that this is the same as the configuration above in Ivy, as the
`aotSummaries` value provided has no effect.
The user intent here is interpreted as follows:
1) `FooCmp` is a pre-existing component that's being used in the test
(via import of `FooModule`). It may or may not be exported by this
module.
2) `FooCmp` should be part of the testing module's scope. That is, it
should be visible to `TestFixture`. This is because it's listed in
`declarations`.
This feature effectively makes the `TestBed` testing module special. It's
able to declare components without compiling them, if they're already
compiled (or configured to be compiled) in the imports. And crucially, the
behavior matches the first example with the summary, making Ivy backwards
compatible with View Engine for tests that use summaries.

Depending on which placeholders the translation uses, there are some legitimate cases where we might not use all placeholder replacements in `i18nPostprocess`. For example if some of the placeholders of the original messages have been removed in the translation.

valid as the guide is only available on `next.angular.io` right now. In order to

major versions), we use the permalink from the `v8` subdomain.
