This contains major changes to the compiler, bootstrap of the platforms and test environment initialization. Main part of #10043 Closes #10164 BREAKING CHANGE: - Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit. This is actually not breaking as `@AppModules` were not part of rc.4. We will have detailed docs on `@NgModule` separately. - `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support). Use `bootstrapModule` / `bootstrapModuleFactory` instead. - All Components listed in routes have to be part of the `declarations` of an NgModule. Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
