The recognizer code used to call Object.freeze() on queryParams before
using them to construct ActivatedRoutes, with the intent being to help
avoid common invalid usage. Unfortunately, Object.freeze() works
in-place, so this was also freezing the queryParams on the actual
UrlTree object, making it more difficult to manipulate UrlTrees in
things like UrlHandlingStrategy.
This change simply shallow-copies the queryParams before freezing them.

When asking the route reuse strategy to retrieve a detached route handle, store the
return value in a local variable for further processing instead of asking again later.

This change brings Angular largely in line with how AngularJS previously serialized URLs. This is based on RFC 3986 and resolves issues such as the above #10280 where URLs could be parsed, re-serialized, then parsed again producing a different result on the second parsing.
Adjustments to be aware of in this commit:
* URI fragments will now serialize the same as query strings
* In the URI path or segments (portion prior to query string and/or fragment), the plus sign (`+`) and ampersand (`&`) will appear decoded
* In the URL path or segments, parentheses values (`(` and `)`) will now appear percent encoded as `%28` and `%29` respectively
* In the URL path or segments, semicolons will be encoded in their percent encoding `%3B`
NOTE: Parentheses and semicolons denoting auxillary routes or matrix params will still appear in their decoded form -- only parentheses and semicolons used as values in a segment or key/value pair for matrix params will be encoded.
While these changes are not considered breaking because applications should be decoding URLs and key/value pairs, it is possible that some unit tests will break if comparing hard-coded URLs in tests since that hard coded string will represent the old encoding. Therefore we are releasing this fix in the upcoming Angular v6 rather than adding it to a patch for v5.

Currently, NavigationStart there is no way to know if an navigation was triggered imperatively or via the location change. These two use cases should be handled differently for a variety of use cases (e.g., scroll position restoration). This PR adds a navigation source field and restored navigation id (passed to navigations triggered by a URL change).

Bazel runs on newer version of RxJs than is installed in Yarn. The never version subclasses `EmptyError` in a different way which fails the `instanceof` check. This change makes the `instanceof` check more robust with respect to `EmptyError`.

Previously, the router would merge path and matrix params, as well as
data/resolve, with special rules (only merging down when the route has
an empty path, or is component-less). This change adds an extra option
"paramsInheritanceStrategy" which, when set to 'always', makes child
routes unconditionally inherit params from parent routes.
Closes#20572.
* The problem was with the `fireChildActivationStart` function. It was taking a `path` param, which was an
array of `ActivatedRouteSnapshot`s. The function was being fired for each piece of the route that was being
activated. This resulted in far too many `ChildActivationStart` events being fired, and being fired on routes
that weren't actually getting activated. This change fires the event only for those routes that are actually
being activated.

* refactor(core): provide error message in stack for reflective DI
Fixes#16355
* fix(compiler): make AOT work with `noUnusedParameters`

* refactor: use view engine also for `NgModuleFactory`s
This is a prerequisite for being able to mock providers

The Router use the type `Params` for all of:
- position parameters,
- matrix parameters,
- query parameters.
`Params` is defined as follow `type Params = {[key: string]: any}`
Because parameters can either have single or multiple values, the type should
actually be `type Params = {[key: string]: string | string[]}`.
The client code often assumes that parameters have single values, as in the
following exemple:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParams
.map(params => params['session_id'] || 'None');
}
}
```
The problem here is that `params['session_id']` could be `string` or `string[]`
but the error is not caught at build time because of the `any` type.
Fixing the type as describe above would break the build because `sessionId`
would becomes an `Observable<string | string[]>`.
However the client code knows if it expects a single or multiple values. By
using the new `ParamMap` interface the user code can decide when it needs a
single value (calling `ParamMap.get(): string`) or multiple values (calling
`ParamMap.getAll(): string[]`).
The above exemple should be rewritten as:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParamMap
.map(paramMap => paramMap.get('session_id') || 'None');
}
}
```
Added APIs:
- `interface ParamMap`,
- `ActivatedRoute.paramMap: ParamMap`,
- `ActivatedRoute.queryParamMap: ParamMap`,
- `ActivatedRouteSnapshot.paramMap: ParamMap`,
- `ActivatedRouteSnapshot.queryParamMap: ParamMap`,
- `UrlSegment.parameterMap: ParamMap`

Before this change there was a single injector tree.
Now we have 2 injector trees, one for the modules and one for the components.
This fixes lazy loading modules.
See the design docs for details:

BREAKING CHANGES
`ComponentFactory.create()` takes an extra optional `NgModuleRef` parameter.
No change should be required in user code as the correct module will be used
when none is provided
DEPRECATIONS
The following methods were used internally and are no more required:
- `RouterOutlet.locationFactoryResolver`
- `RouterOutlet.locationInjector`
