The disableReset feature of QNonContiguousByteDevice is removed as it

When handling signals from the session, a pointer is needed.
Also the QNetworkReplyImpl needs to access the manager's session.
So, the manager should have a strong and weak reference.
The strong reference is held during connection establishment.
The weak reference is held all the time, though it will become
null when the session is destroyed in idle.
The non static member function getNetworkSession() is used to
create strong references from the weak reference where required.

When two threads construct a QNetworkAccessManager at exactly the
same time on an SMP system, there are construction races for some
Q_GLOBAL_STATIC data. This is normal and expected - the losing
thread deletes its instance as part of the Q_GLOBAL_STATIC macro.

For QNetworkAccessBackendFactoryData, a guard mechanism intended
to prevent the data being reconstructed by destructors of other
global static classes was being set by the loser.
To fix this, the bool is changed to a QAtomicInt. In the normal
case, it will have value 0->1 on startup and 1->0 on shutdown.
In the race case, it will have values 0->1->2->1 on startup and
1->0 on shutdown.
