QByteArray: inline QByteArray::isNull()

Browse Source 
Keeping it out-of-line is unnecessary and has been since 5.0. In Qt 4.x,
it was necessary to compare to the shared_null, which for QByteArray was
a static variable. The one for QString has always been inline because
the shared null was a static member of QString (in Qt 3, QString::null
was a QString variable).
