[9] RFR of 8087288: File.get{Free, Total, Usable}Space may return unexpected results with >2TB file systems

[Brian Burkhalter]

Please review at your convenience:

Issue:	https://bugs.openjdk.java.net/browse/JDK-8087288
Patch:	http://cr.openjdk.java.net/~bpb/8087288/webrev.00/

The root cause of this problem is essentially the same as that of https://bugs.openjdk.java.net/browse/JDK-8081843 and the proposed fix is likewise similar: on Mac OS X replace statvfs64() and struct statvfs64 with statfs() and struct statfs, respectively, and f_frsize with f_bsize.

Thanks,

Brian
