Better NewIO2 file system implementation for AIX platform

[deven you]

Hi All,

Our current NIO2 file system support to AIX is very limited, hence I took
some time to try to complete it. Openjdk bug[1] tracks this bug and here is
my patch[2] which enhances the AIX file system especially by adding the
support by Implementing AixDosFileAttributeView.java and
AixUserDefinedFileAttributeView.java.

Could anyone take a look?

Thanks a lot!
