QNetworkReply: hold QAtomicInt in shared_ptr, not QSharedPointer

Ditto QNetworkAccessAuthenticationManager.

QSharedPointer performs twice as many atomic operations per pointer
copy as std::shared_ptr, and this is private API, we're not bound by
BC constraints, so we can port to the more efficient version.
