QEventLoopLocker: rewrite to hold public classes

... 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.
