Sometimes when we force a session regeneration we want to update the
current token for this session.

* We first try the email as username but this fails
* Then we get the uid from the email and try again
We should not log the first attempt since it polutes the log with failed
login attempts while the login actually is valid.

The CSP nonce is based on the CSRF token. This token does not change,
unless you log in (or out). In case of the session data being lost,
e.g. because php gets rid of old sessions, a new CSRF token is gen-
erated. While this is fine in theory, it actually caused some annoying
problems where the browser restored a tab and Nextcloud js was blocked
due to an outdated nonce.
The main problem here is that, while processing the request, we write
out security headers relatively early. At that point the CSRF token
is known/generated and transformed into a CSP nonce. During this request,
however, we also log the user in because the session information was
lost. At that point we also refresh the CSRF token, which eventually
causes the browser to block any scripts as the nonce in the header
does not match the one which is used to include scripts.
This patch adds a flag to indicate whether the CSRF token should be
refreshed or not. It is assumed that refreshing is only necessary
if we want to re-generate the session id too. To my knowledge, this
case only happens on fresh logins, not when we recover from a deleted
session file.

The encryption app relies on the post_login hook to initialize its keys.
Since we do not emit it on a remembered login, the keys were always un-
initialized and the user was asked to log out and in again.
This patch *translates* the postRememberedLogin hook to a post_login
hook.

Else the last-login-check fails hard because the session value is not
set and thus defaults to 0.

We have to respect the value of the remember-me checkbox. Due to an error
in the source code the default value for the session token was to remember
it.

Use firstLogin event to trigger creation of default calendar and default address book
Delay login of admin user after setup so that firstLogin event can properly be processed for the admin
Fixing tests ...
Skeleton files are not copied over -> only 3 cache entries are remaining
Use updateLastLoginTimestamp to properly setup lastLogin value for a test user
* try to reuse the old session token for remember me login
* decrypt/encrypt token password and set the session id accordingly
* create remember-me cookies only if checkbox is checked and 2fa solved
* adjust db token cleanup to store remembered tokens longer
* adjust unit tests

The check for two factor enforcement would return true for non-existing
users. This fix makes it return false in order to be able to perform
the regular login which will then fail and return false.
This prevents throwing PasswordLoginForbidden for non-existing users.
Class Throttler implements the bruteforce protection for security actions in
Nextcloud.
It is working by logging invalid login attempts to the database and slowing
down all login attempts from the same subnet. The max delay is 30 seconds and
the starting delay are 200 milliseconds. (after the first failed login)
