DLC Decryption

[onelight]

I've improved Xuggler's memory handling in r3433. I've also added a small fix in sceUtility for the behavior displayed by MHP3.
Could you please check if MHP3 and AKB149 are now working properly? Thanks!

Thinks you fix MHP3 and AKB149, now AKB149 can load in the sound is good. but
AKB149 DLC not work
MHP3 couldnot save if you not check Handle SAVEDATA in crypto mode

I think PPSSPP is good at savedata , it can read savedata Encryption/Decryption Type （not need check anything) ,it can save in Encryption Type if you use EncryptSave = True or save in Decryption Type if you use EncryptSave = Flase. and psp can use ppsspp savedata if savedata is Encryption Type.
