QDebug: Allow text stream formatting for 64 bit numbers

Use the QTextStream stream operator for formatting 64 bit numbers,
just like we do for other numbers, too. This ensures all numbers in
a QDebug stream e.g. respect the hex and showbase modifiers.

The original reason for formatting qin64, quint64 with QString::number
is unclear (pre-dates the original qt4 git import). Maybe QTextStream
did lack proper support for 64 bit numbers back then.
