To continue this formatting madness, here's a tiny patch that adds
unified formatting for control structures like if and loops as well as
classes, their methods and anonymous functions. This basically forces
the constructs to start on the same line. This is not exactly what PSR2
wants, but I think we can have a few exceptions with "our" style. The
starting of braces on the same line is pracrically standard for our
code.
This also removes and empty lines from method/function bodies at the
beginning and end.

Otherwise we keep on using it with leading or trailing whitespaces for
app tokens and other logic. The reason this doesn't throw an error
immediately with local users is that (My)SQL compares strings regardless
of their padding by default. So we look up 'uid ' and get the row for
the user 'uid'.
Other back-ends will lead to a hard error, though, and the user is
unable to log out as all request fail.

Only when an avatar is set to public should we show it to the public.
For now this has an open question as to how to solve federated avatars.

There is no need to log the expcetion of most of the stuff here.
We should properly log them but an exception is excessive.
This moves it to a proper exception which we can catch and then log.
The other exceptions will still be fully logged.

The constructor is called with the userId. However if a user is not
logged in this is null. Which means that we get an exception instead of
this being handled gracefully in the middleware.
There are cleaner solutions. But this is the solution that is the
easiest to apply without lots of work and risk of breaking things
(handling the logged in middleware before initializing the controller
etc).

Since the clearing of the execution context causes another reload. We
should not do the redirect_uri handling as this results in redirecting
back to the logout page on login.
This adds a simple middleware that will just check if the
ClearExecutionContext session variable is set. If that is the case it
will just redirect back to the login page.

When a password is reste we should make sure that all users are properly

this is checked (within 5 minutes).

If the remember_login_cookie_lifetime is set to 0 this means we do not
want to use remember me at all. In that case we should also not creatae
a remember me cookie and should create a proper temp token.
Further this specifies that is not 0 the remember me time should always
be larger than the session timeout. Because else the behavior is not

Because the redirect from the SAML/SSO endpoint is a POST the lax/strict

In 2f87fb6b45 this header was introduced. The referenced documentation says:
> When delivered with a response from https://example.com/clear, the following header will cause cookies associated with the origin https://example.com to be cleared, as well as cookies on any origin in the same registered domain (e.g. https://www.example.com/ and https://more.subdomains.example.com/).
This also applies if `https://nextcloud.example.com/` sends the `Clear-Site-Data: "cookies"` header.
This is not the behavior we want at this point!
So I removed the deletion of cookies from the header. This has no effect on the logout process as this header is supported only recently and the logout works in old browsers as well.

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.
