So fun fact. Chrome considers a redirect after submitting a form part of
the form actions. Since we redirect to a new protocol (nc://login/).
Causing the form submission to work but the redirect failing hard.

This can be used by pages that do not have the full Nextcloud UI.
So notifications etc do not load there.

It seems iOS doesn't like us to change the location. So now we submit it
to the server that geneartes the redirect.

Because the redirect from the SAML/SSO endpoint is a POST the lax/strict
cookies are not properly send.
Note that it is not strictly requried on this endpoint as we do not need
the remember me data. Only the real session info is enough. The endpoint
is also already protected by a state token.

If a user can't authenticate normally (because they have 2FA that is not
available on their devices for example). The redirect that is generated
should be of the proper format.
This means
1. Include the protocol
2. Include the possible subfolder

Fixes#10584
We deleted the main token when using the login flow else mutliple tokens
would show up for a single user.
However in the case of OAuth this is perfectly fine as the
authentication happens really in your browser:
1. You are already logged in, no need to log you out
2. You are not logged in yet, but since you log in into the exact same
browser the expected behavior is to stay logged in.

PHPDoc (of the public API) says that this method returns string but it also returns null, which is not allowed in some method calls. This fixes that behaviour and returns an empty string and fixes all code paths that explicitly checked for null to be still compliant.
Found while enabling the strict_typing for lib/private for the PHP7+ migration.

Fixes#7697
When using the new login flow a token will be generated since we login.
However after that we generate yet another token to return (as we
should).
However we should kill the current session token as we are done with it.
And will never use it again.

This implements the basics for the new app-password based authentication flow for our clients.
The current implementation tries to keep it as simple as possible and works the following way:
1. Unauthenticated client opens `/index.php/login/flow`
2. User will be asked whether they want to grant access to the client
3. If accepted the user has the chance to do so using existing App Token or automatically generate an app password.
If the user chooses to use an existing app token then that one will simply be redirected to the `nc://` protocol handler.
While we can improve on that in the future, I think keeping this smaller at the moment has its advantages. Also, in the
near future we have to think about an automatic migration endpoint so there's that anyways :-)
If the user chooses to use the regular login the following happens:
1. A session state token is written to the session
2. User is redirected to the login page
3. If successfully authenticated they will be redirected to a page redirecting to the POST controller
4. The POST controller will check if the CSRF token as well as the state token is correct, if yes the user will be redirected to the `nc://` protocol handler.
This approach is quite simple but also allows to be extended in the future. One could for example allow external websites to consume this authentication endpoint as well.
