Add QArrayData::sharedNullData()
Just to simplify a few operations, like detecting when a QChar* or char*
coming from a QString or QByteArray, respectively, were null data.
While you're not supposed to dereference the pointer returned by
QVector::data() unless you know that the array is non-empty, that is
permitted for QString and QByteArray. That is, QString().constData()
must return a valid pointer to a null QChar.
