Modify the virtual streams so no seek is necessary when streamReader::getReader() is called

[Paolo Brandoli]

When streamReader::getReader() is called the stream reader's buffer may already contain the data needed by the returned virtual stream.

This may cause the new virtual stream to seek backward and to reread the content already read.
