PHP 8.4 deprecation warnings for nullable parameters

[NiLon]

There seems to be flood of deprecation warnings for nullable parameters all around the codebase. This bubbles down to other libs as well.

Deprecated: ByJG\DbMigration\Migration::reset(): Implicitly marking parameter $upVersion as nullable is deprecated, the explicit nullable type must be used instead

This style is deprecated:

function foo(string $bar = null) { }

Instead it has to be:

function foo(?string $bar = null) { }

Thanks for letting us know.

We are starting to add the PHP 8.4 compatibility to all dependent classes. So far, we started the branch 5.1 on the highlighted boxes.

In the middle of the process, we found the anydataset-array will be deprecated and we will use anydataset instead. As soon we update this I'll let you know.
