Changed the lock names and added the locks around (de)scrambling (attached as
separate patch and as updated full one), but one of the prevoiusly sent
patches (0006a) does only this and I have skipped it, because corruption may
happen only when the active (in use) key is changed and in such case there
will be corupted frames in either case, as it can never happen at the same
frame on the server and the client, so this should save some CPU. If the key
in use is changed it won't cause corruption (on scrambling).
