ActivatedRoute.fragment was typed as Observable<string> but could emit
both null and undefined due to incorrect non-null assertion. These
non-null assertions have been removed and fragment has been retyped to
string | null.
BREAKING CHANGE:
Strict null checks will report on fragment potentially being null.
Migration path: add null check.
Fixes#23894, fixes#34197.

Fix a case where matrix parameters weren't stringified when they are passed as a first command
when creating a url tree. Fix return type in parseMatrixParams method
because it always returns {[key: string]: string}
Closes#23165
PR Close#25095
There are many places where examples use just a string for the command
in outlets. When using nested outlets, we do not correctly handle
this case, as the types and algorithm always expect an array.
This PR updates the `createUrlTree` algorithm to account for the
possibility of a string literal as the command for an outlet.
Fixes#18928
PR Close#39728
When there is a primary outlet present in the outlets map and the object is also prefixed
with some other commands, the current logic only uses the primary outlet and ignores
the others. This change ensures that all outlets are respected at the
segment level when prefixed with other commands.

This commit has a small refactor of some methods in create_url_tree.ts
and adds some test cases, including two that will fail at the moment but
should pass. A follow-up commit will make use of the refactorings to fix
the test with minimal changes.

Value of "undefined" passed as segment in routerLink is stringified to string "undefined".
This change introduces the same behavior for value of "null".
PR Close#32616
For URLs that use auxiliary route outlets in the second or following path segments,
when removing the auxiliary route segment, parenthesis remain for the primary outlet segment.
This causes the following error when trying to reload an URL: "Cannot match any route".
The commit adds a check for this scenario, serializing the URL as "a/b" instead of "a/(b)".

Partial resubmit of #26243
Fixes incorrect url tree generation for empty path components with children.
Adds a test to demonstrate the failure of createUrlTree for those routes.
Fixes#13011Fixes#35687
PR Close#37446
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`
