6516099: InputStream.skipFully(int k) to skip exactly k bytes

Hi Brian,

I am not sure whether you can trust that a skip implementation
that returns -1 has actually rewind 1 byte - for instance:


Not sure there's anything that could be done in such cases, except
encouraging such subclasses to provide their own implementation
of skipNBytes?

best regards,
