RFR(S): 8201649: Remove dubious call_jio_print in ostream.cpp

Ok, I agree. So I tried to clarify the bug a bit more in its original sense. And we'd be back to webrev #0.

Bug: https://bugs.openjdk.java.net/browse/JDK-8201649
Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8201649.0/

The change of the webrev is missing a cast in line 2729 - (len needs to be casted int). This produces a build warning which turns into an error in some platforms. I'll have that fixed in the submitted version.

For the further cleanup of jio_print methods I'll probably file another bug.

As I think we already had a principal agreement about this proposal earlier, I would consider this reviewed by stuefe and dholmes if I don't hear back from you today. I would push this tomorrow after push to jdk-submit and further internal testing here at SAP.

Thanks
Christoph
