The session token renewal does
1) Read the old token
2) Write a new token
3) Delete the old token
If two processes succeed to read the old token there can be two new tokens because
the queries were not run in a transaction. This is particularly problematic on
clustered DBs where 1) would go to a read node and 2) and 3) go to a write node.

This is an helpful helper that should be used in more place than just
server and this is already the case with groupfodlers, deck, user_oidc
and more using it, so let's make it public

For passwords bigger than 250 characters, use a bigger key since the
performance impact is minor (around one second to encrypt the password).
For passwords bigger than 470 characters, give up earlier and throw
exeception recommanding admin to either enable the previously enabled
configuration or use smaller passwords.

This adds an option to disable storing passwords in the database. This
might be desirable when using single use token as passwords or very
large passwords.

The auth token activity logic works as follows
* Read auth token
* Compare last activity time stamp to current time
* Update auth token activity if it's older than x seconds
This works fine in isolation but with concurrency that means that
occasionally the same token is read simultaneously by two processes and
both of these processes will trigger an update of the same row.
Affectively the second update doesn't add much value. It might set the
time stamp to the exact same time stamp or one a few seconds later. But
the last activity is no precise science, we don't need this accuracy.
This patch changes the UPDATE query to include the expected value in a
comparison with the current data. This results in an affected row when
the data in the DB still has an old time stamp, but won't affect a row
if the time stamp is (nearly) up to date.
This is a micro optimization and will possibly not show any significant
performance improvement. Yet in setups with a DB cluster it means that
the write node has to send fewer changes to the read nodes due to the
lower number of actual changes.

For historic reasons we couldn't add a nullable type hint before
nullable type hints were supported by our target php versions. This is
now possible.

Else you can end up that you renewed your password (LDAP for example).
But they still don't work because you did not use them before you logged
in.

On some systems with a lot of users this creates a lot of extra DB
writes.
Being able to increase this interval helps there.

When your password changes out of bounds your Nextcloud tokens will
become invalid. There is no real way around that. However we should make
sure that if you successfully log in again your passwords are all
updates
* Added event listener to the PostLoggedInEvent so that we can act on it
- Only if it is not a token login
* Make sure that we actually reset the invalid state when we update a
token. Else it keeps being marked invalid and thus not used.

This avoids hitting the backend with multiple requests for the same
token. And will help avoid quick LDAP lockouts.

Avoids directly getting the token again. We just inserted it so it and
have all the info. So that query is just a waste.

Sometimes (esp with token auth) we query the same token multiple times.
While this is properly indexed and fast it is still a bit of a waste.
Right now it is doing very stupid caching. Which gets invalidate on any
update.

This allows a user to mark a token for remote wipe.
Clients that support this can then wipe the device properly.

* On weblogin check if we have invalid public key tokens
* If so update them all with the new token
This ensures that your marked as invalid tokens work again if you once
login on the web.

* When getting the token
* When rotating the token
* Also store the encrypted password as base64 to avoid weird binary
