Add back QByteArray's relational operators taking QString
QString still has the overloads of relational operators taking
QByteArray. Add back QByteArray's relational operators taking
QString for symmetry. See also the comments of
d7ccd8cb4565c8643b158891c9de3187c1586dc9 for more details.
[ChangeLog][EDITORIAL] Remove the changelog about QString/QByteArray
operators being removed. They're back.
