Subject: Add explicit network session support for async QHostInfo

Pass the shared network session pointer into the QSymbianHostResolver
(which maintains a reference for its lifetime). This is used to open
the RHostResolver handle, in order to get a host resolver which is
associated with a particular session.
The session is obtained from the _q_networksession property of the
QAbstractSocket, as in the symbian socket engine
