RFR(S): AIX only: Integrate fixes of 7178026 and other minor things to AIX perfMemory and attachListener

[Langer, Christoph]

Hi,

I’ve integrated some changes that have been done in the perfMemory and attachListener implementations of the Linux/Unix platforms to the AIX counterpart. They have obviously been missing there so far.

This is the webrev: http://cr.openjdk.java.net/~clanger/webrevs/8150232.0/
This is the bug: https://bugs.openjdk.java.net/browse/JDK-8150232

Please review and push if no objections. I’ve run a build on AIX successfully ☺

Thanks
Christoph
