For the Google Cloud Console within Google we observed errors in the
shallowEqual function for users in IE and Edge. This patch was made within
Google and the errors went away. This commit upstreams the change into Angular.

When loading a module that doesn't provide `RouterModule.forChild()` preloader will get stuck
in an infinite loop and throw `ERROR Error: Maximum call stack size exceeded.`
The issue is that child module's `Injector` will look to its parent `Injector` when it doesn't
find any `ROUTES` so it will return routes for it's parent module instead. This will load the
child again that returns its parent's routes and so on.

During route activation, a componentless route will not have a context created
for it, but the logic continues to recurse so that children are still
activated. This can be seen here:
362f45c4bf/packages/router/src/operators/activate_routes.ts (L151-L158)
The current deactivation logic does not currently account for componentless routes.
This commit adjusts the deactivation logic so that if a context cannot
be retrieved for a given route (because it is componentless), we
continue to recurse and deactivate the children using the same
`parentContexts` in the same way that activation does.

When talking about parameter inheritance, one might think that matrix
parameters can be inherited from the "parent" segment, or the segment
which appears immediately to the left. In reality, when we talk about
a "parent" in the `Router`, we mean the parent `Route` config. This
config may contain more than one segment and matrix parameters must
appear at the end or they do not "belong" to any config.

There are two parts to this commit:
1. Revert the changes from #38379. This change had an incomplete view of
how things worked and also diverged the implementations of
`applyRedirects` and `recognize` even more.
2. Apply the fixes from the `recognize` algorithm to ensure that named
outlets with empty path parents can be matched. This change also passes
all the tests that were added in #38379 with the added benefit of being
a more complete fix that stays in-line with the `recognize` algorithm.
This was made possible by using the same approach for `split` by
always creating segments for empty path matches (previously, this was
only done in `applyRedirects` if there was a `redirectTo` value). At the
end of the expansions, we need to squash all empty segments so that
serializing the final `UrlTree` returns the same result as before.

PR Close#40029
The `applyRedirects` and `recognize` algorithms have the same overall goal:
match a `UrlTree` with the application's `Routes` config. There are a
few key functions in these algorithms which can be shared rather than
duplicated between the two. This also makes it easier to see how the two
are similar and where they diverge.
PR Close#40029
This commit updates the `recognize` algorithm to work with named outlets
which have empty path parents. For example, given the following config
```
const routes = [
{
path: '',
children: [
{path: 'a', outlet: 'aux', component: AuxComponent}
]}
];
```
The url `/(aux:a)` should match this config. In order to do so, we need
to allow the children of `UrlSegmentGroup`s to match a `Route` config
for a different outlet (in this example, the `primary`) when it's an
empty path. This should also *only* happen if we were unable to find a
match for the outlet in the level above. That is, the matching strategy
is to find the first `Route` in the list which _matches the given
outlet_. If we are unable to do that, then we allow empty paths from
other outlets to match and try to find some child there whose outlet
matches our segment.

To make the tests suite easier to follow, `Recognize#apply` can be made
into a synchronous function rather than one that return an `Observable`.
Also, as a chore, remove as many `any` types as possible.
PR Close#40029
This commit updates the `recognize` algorithm to return `null` when a
segment does not match a given config rather than throwing an error.
This makes the code much easier to follow because the "no match" result
has to be explicitly handled rather than catching the error in very
specific places.
PR Close#40029
When stepping through the `recognize` algorithm, it is much easier to
follow when using a simple `for...of` rather than the helper
`mapChildrenIntoArray` with the passed closure. The only special thing that
`mapChildrenIntoArray` does is ensure the primary route appears first.
This change will have no affect on the result because `processChildren` later calls
`sortActivatedRouteSnapshots`, which does the same thing.

Redirects in the router are processed before activations. This means that a canActivate will
never execute if a route has a redirect. Rather than silently ignoring
the invalid config, developers should be notified so they know why it
doesn't work.

Allow configuration of `relativeTo` in the `routerLink` directive. This
is related to the clearing of auxiliary routes, where you need to use
`relativeTo: route.parent` in order to clear it from the activated
auxiliary component itself. This is because `relativeTo: route` will
consume the segment that we're trying to clear, so there is really no
way to do this with routerLink at the moment.

There are many places where examples use just a string for the command

The codebase currently contains two `getOutlet` functions,
and they can end up in the bundle of an application.
A recent commit 6fbe21941d tipped us off
as it introduced several `noop` occurrences in the golden symbol files.
After investigating with @petebacondarwin,
we decided to remove the duplicated functions.
This probably shaves only a few bytes,
but this commit removes the duplicated functions,
by always using the one in `router/src/utils/config`.

As of Angular v4, four of the options for
`ExtraOptions#initialNavigation` have been deprecated. We intend
to remove them in v11. The final state for these options is:
`enabledBlocking`, `enabledNonBlocking`, and `disabled`. We plan
to remove and deprecate the remaining option in the next two
major releases.
New options:
- `enabledNonBlocking`: same as legacy_enabled
- `enabledBlocking`: same as enabled
BREAKING CHANGE:
* The `initialNavigation` property for the options in
`RouterModule.forRoot` no longer supports `legacy_disabled`,
`legacy_enabled`, `true`, or `false` as valid values.
`legacy_enabled` (the old default) is instead `enabledNonBlocking`
* `enabled` is deprecated as a valid value for the
`RouterModule.forRoot` `initialNavigation` option. `enabledBlocking`
has been introduced to replace it

This make it coherent with typing of Router.createUrlTree to which
those inputs are directly forwarded to. And hence it allow to pass

BREAKING CHANGE: in most cases this should not break, but if you were
accessing the values of `queryParams`, `fragment` or `queryParamsHandling`
you might need to relax the typing to also accept `undefined` and `null`.

In certain circumstances (errors during component constructor) the router outlet may not be activated before
redirecting to a new route. If the new route requires running guards and resolvers the current logic will throw

logic inline with deactivateRouterAndItsChildren, namely checking outlet.isActivated before trying to access
outlet.component.

`router.navigateByUrl` and `router.createUrlTree` only use a subset of the `NavigationExtras`. This commit
changes the parameter type to use new interfaces that only specify the properties used by
those function implementations. `NavigationExtras` extends both of those interfaces.
Fixes#18798
BREAKING CHANGE: While the new parameter types allow a variable of type
`NavigationExtras` to be passed in, they will not allow object literals,
as they may only specify known properties. They will also not accept
types that do not have properties in common with the ones in the `Pick`.
To fix this error, only specify properties from the `NavigationExtras` which are
actually used in the respective function calls or use a type assertion
on the object or variable: `as NavigationExtras`.

specifically specify `'legacy'` for `relativeLinkResolution`.

The `createOrReuseChildren` function calls shouldReuseRoute with the
previous child values use as the future and the future child value used
as the current argument. This is incosistent with the argument order in
`createNode`. This inconsistent order can make it difficult/impossible
to correctly implement the `shouldReuseRoute` function. Usually this
order doesn't matter because simple equality checks are made on the
args and it doesn't matter which is which.
More detail can be found in the bug report: #16192.
Fix#16192
BREAKING CHANGE: This change corrects the argument order when calling
RouteReuseStrategy#shouldReuseRoute. Previously, when evaluating child
routes, they would be called with the future and current arguments would
be swapped. If your RouteReuseStrategy relies specifically on only the future
or current snapshot state, you may need to update the shouldReuseRoute
implementation's use of "future" and "current" ActivateRouteSnapshots.

In general, the router only matches and loads a single Route config tree. However,
named outlets with empty paths are a special case where the router can
and should actually match two different `Route`s and ensure that the
modules are loaded for each match.
This change updates the "ApplyRedirects" stage to ensure that named
outlets with empty paths finish loading their configs before proceeding
to the next stage in the routing pipe. This is necessary because if the
named outlet has `loadChildren` but the associated lazy config is not loaded
before following stages attempt to match and activate relevant `Route`s,
an error will occur.
