Experimental commit: this is the base for a more complex dlist control code, is incomplete but i need some feedback. 

whit this code hashing is completely disabled for the dlists content itself this must bring some fps more but i must know if this causes any glitches.
i suspect that no game modify the content of the dlist so hash is time wasted but the only way to test it is with this commit.
please test as many games s you can and give me feedback for any glitch.
