ngc can now validate metadata before emitting to verify it doesn't
contain an error symbol that will result in a runtime error if
it is used by the StaticReflector.
To enable this add the section,
"angularCompilerOptions": {
"strictMetadataEmit": true
}
to the top level of the tsconfig.json file passed to ngc.
Enabled metadata validation for packages that are intended to be
used statically.
Prior to this change `ngc` would place generated files which refer
to components in the node_modules into the node_module. This is an
issue. Now all of the files are forced into a single directory
as specified in `tsconfig.json` by the `genDir` option.

RelectorHost threw an exception when metadata was requested for a
.d.ts file that didn't have a .metadata.json file. Changed it to
return undefined.

This introduces the `BrowserModule` to be used for long form
bootstrap and offline compile bootstrap:
```
@AppModule({
modules: [BrowserModule],
precompile: [MainComponent],
providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {
constructor(appRef: ApplicationRef) {
appRef.bootstrap(MainComponent);
}
}
// offline compile
import {bootstrapModuleFactory} from ‘@angular/platform-browser’;
bootstrapModuleFactory(MyModuleNgFactory);
// runtime compile long form
import {bootstrapModule} from ‘@angular/platform-browser-dynamic’;
bootstrapModule(MyModule);
```
The short form, `bootstrap(...)`, can now creates a module on the fly,
given `directives`, `pipes, `providers`, `precompile` and `modules`
properties.
Related changes:
- make `SanitizationService`, `SecurityContext` public in `@angular/core` so that the offline compiler can resolve the token
- move `AnimationDriver` to `platform-browser` and make it
public so that the offline compiler can resolve the token
BREAKING CHANGES:
- short form bootstrap does no longer allow
to inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead.
To provide custom providers for the compiler,
create a custom compiler via `browserCompiler({providers: [...]})`
and pass that into the `bootstrap` method.
Also modified static reflector to allow writing tests in using
the .ts and using the MetadataCollector.
Also made MetadataCollector be able to use SourceFiles that have
not been bound (that is, don't have the parent property set).
Fixes#9182Fixes#9265
The collector now collects the body of functions that return an
expression as a symbolic 'function'. The static reflector supports
expanding these functions statically to allow provider macros.
Also added support for the array spread operator in both the
collector and the static reflector.
Refactored ReflectorHost to allow it to be tested.
Fixed an issue where the .d.ts was findable but it wasn't used by the project
(This happens when the .metadata.json file references a module that was not
needed, such as it doesn't declare any types, and the reference to it was
elided by TypeScript when writing the .d.ts file).
Added tests for ReflectorHost
StaticReflector provides more context on errors reported by the
collector.
The metadata collector now records the line and character of the node that
caused it to report the error.
Includes other minor fixes to error reporting and a wording change.
