RFR 4358774: Add null InputStream and OutputStream

[Brian Burkhalter]

Hi Roger,

I agree. It does not seem that whatever performance improvement might accrue from not using the Objects methods is offset by the increased code readability in addition to mitigating the risks mentioned in [1]. I have reinstated this approach in http://cr.openjdk.java.net/~bpb/4358774/webrev.02/.

Thanks,

Brian
