qt, cpp: Support larger size-hint on 32 bit builds

* NEWS: Mention this.
* lang/cpp/src/data.h, lang/cpp/src/data.cpp (Data::setSizeHint): New.

 lang/qt/src/qgpgmeverifyopaquejob.cpp: Set size for input IODevice.

--
This fixes the case where the old detection of the size of QIOdevice
using seek would overflow and instead explicitly uses QIODevice::size
to check for the size and pass it through as an uint64.
