Add QDebug::noquote() stream modifier

Allow the user to disable the quoting of QString, QByteArray,
QStringLiteral by passing a "noquote()" stream modifier.

This requires another flag to be added to QDebug::Stream. To
keep BC we're using the QMessageLogContext::version field
to differentiate between QDebug streams created by earlier
versions.
