Fix QTextStream::pos() causes buffer offset issues on large text files.

 When reading large files that are greater in size than the
TEXTSTREAM_BUFFERSIZE buffer, calling pos() caused erroneous buffer
positioning. The cause of this was QTextStreamPrivate::readBufferOffset
value being updated, but QTextStreamPrivate::readConverterSavedStateOffset
was not.  Usually, if pos() is called, it is called multiple times. Since
QTextStreamPrivate::readConverterSavedStateOffset was never reset,
QTextStreamPrivate::readBufferOffset would accumulate the wrong position
and QTextStreamPrivate::consume() will 'discard' the wrong number of
bytes from the buffer.
