Added new functions to QTextCodec that accept ConversionFlags.
In some cases the user might want to pass initial conversion flags that should be used by the QTextEncoder and QTextDecoder, so added convenience QTextCodec::makeDecoder and makeEncoder functions that accept those flags as an argument. Task-number: QTBUG-7180 Reviewed-by: Thiago
