This is a major refactor of how the router previously worked. There are a couple major advantages of this refactor, and future work will be built on top of it.
First, we will no longer have multiple navigations running at the same time. Previously, a new navigation wouldn't cause the old navigation to be cancelled and cleaned up. Instead, multiple navigations could be going at once, and we imperatively checked that we were operating on the most current `router.navigationId` as we progressed through the Observable streams. This had some major faults, the biggest of which was async races where an ongoing async action could result in a redirect once the async action completed, but there was no way to guarantee there weren't also other redirects that would be queued up by other async actions. After this refactor, there's a single Observable stream that will get cleaned up each time a new navigation is requested.
Additionally, the individual pieces of routing have been pulled out into their own operators. While this was needed in order to create one continuous stream, it also will allow future improvements to the testing APIs as things such as Guards or Resolvers should now be able to be tested in much more isolation.
* Add the new `router.transitions` observable of the new `NavigationTransition` type to contain the transition information
* Update `router.navigations` to pipe off of `router.transitions`
* Re-write navigation Observable flow to a single configured stream
* Refactor `switchMap` instead of the previous `mergeMap` to ensure new navigations cause a cancellation and cleanup of already running navigations
* Wire in existing error and cancellation logic so cancellation matches previous behavior

All directives and pipes must now be tagged with one ore more
public NgModule, from which they are exported.
If an item is exported transitively via a re-exported internal NgModule
then it may be that the item appears to be exported from more than
one public NgModule. For example, there are shared directives that
are exported in this way from `FormsModule` and `ReactiveFormsModule`.
The doc-gen will error and fail if a directive or pipe is not tagged correctly.
NgModule pages now list all the directives and pipes that are exported from it.
Directive and Pipe pages now list any NgModule from which they are exported.
Packages also now list any NgModules that are contained - previously they were
missed.

`TypeScript` only supports merging and extending of `compilerOptions`. This is an implementation to support extending and inheriting of `angularCompilerOptions` from multiple files.

Firebase used to do it automatically (with `cleanUrls: true`), but it
stopped doing it unless the resulting URL corresponds to an existing
file (which is not always the case in angular.io; e.g. the resulting URL
might be matched by a new redirect rule).
This change in Firebase hosting behavior resulted in some URLs not being
correctly redirected (e.g. URLs to the archived v2 site, or `.html`
suffixed URLs from 3rd-party sites).
This commit fixes it, by configuring Firebase hosting to strip off the
`.html` extension and redirect (if no other redirect rule matched).
