... instead of Private ones, at the cost of having to befriend of all the lockable classes, because we need access to their d_func()'s. This simplifies the code, because we don't need the manual QClass to QClassPrivate mapping (o2p) anymore, we can just use d_func(). This also paves the way to make QEventLoopLocker almost completely inline and use a 3-pointer form of QBiPointer, once available, to hide the bit fiddling. We couldn't make such a change if the class continued to hold pointers to QClassPrivate's.
