Description

We currently have a few things in our ViewState handling which could get even further improved.
There are 3 main goals we achieve (in order of importance):

1.) security - it should not be easily possible to create state key clashes
2.) performance - we still use java 1.3 tricks and e.g. barely use java.util.concurrent
3.) memory - we shall keep the mem footprint as low as possible
