the old names still exist as deprecated aliases for the time being.
* Introduced hooks FirstReferenceAcquired() and LastReferenceReleased(). Besides
added flexibility this also makes the deleteWhenUnreferenced constructor
parameter and the fDeleteWhenUnreferenced attribute superfluous, since the
"don't delete" behavior can be obtained by overriding LastReferenceReleased().
Parameter and attribute will be removed eventually.
