Long live qCompareStrings()!
These free functions are designed to solve the problem that we
currently have QString::compare(QString, QString), but we have no
QString::compare(QStringRef, QString), even though we have
QString::compare(QStringRef). A compare(QString, QStringRef) only
exists in QStringRef.
This makes writing generic code tedious and error prone.
Notably absent are comparisons involving char* and QByteArray. These
will be added when we add QUtf8String, the UTF-8 counterpart to
QLatin1String.
