De-inline QIODevice::write(const QByteArray &)

Since QRingBuffer is used as a temporary store for data to be written
to a buffered device, we can implement a "zero-copy" strategy between
the user-space code and QIODevice's internal write buffer. As a first
step, we should have an entry point, where we can implement a possible
solution.
