let QWindowsPipeReader::stop() cancel the current I/O operation
In rare cases the I/O operation was still running after the destructor
was running, which then modified free'd memory and caused a malformed
heap. To prevent this, we ensure that QWindowsPipeReader::stop() cancels
a running I/O operation and sets the readSequenceStarted flag correctly.
Also, we prevent the start of a new read operation after we called stop().
