Proposal for adding O_DIRECT support into JDK 9

[Brian Burkhalter]

Hi Lucy,

Per the JDK 10 repository consolidation [1], the Direct I/O patch needed some minor reshuffling. I have created a patch re-based to the new JDK 10 master [2]. Unless I missed something, the differences are:

make/test/JtregNative.gmk -> make/test/JtregNativeJdk.gmk with some content update
test/java/nio -> test/jdk/java/nio
removal of some trailing white spaces in the Windows version of FileDispatcherImpl.c

I tested this locally on macOS and am running it presently through our test harness.

Thanks,

Brian
