Make all php classes strict #17
Description
Description
If you look at code like https://github.com/nextcloud/server/blob/master/apps/dav/lib/DAV/CustomPropertiesBackend.php then you see that not all of our php code has declare(strict_types=1); yet.
It's time to clean this up, force PHP into strict mode and out of unpredictable type juggling. This might cause some errors, but they are valid and should be fixed.

To do
