RFR (S): 8004172: Update jstat counter names to reflect metaspace changes

[Erik Helin]

Hi all,

here are the JDK changes for fixing JDK-8004172. This change updates the 
jstat resource file to use the new metaspace performance counters and 
also updates the tests.

Note that the fixed tests will continue to fail until the HotSpot part 
of the change finds it way into the tl forest.

The HotSpot part of the change is also out for review on 
hotspot-gc-dev at openjdk.java.net.

Webrev:
JDK: http://cr.openjdk.java.net/~ehelin/8004172/jdk/webrev.00/
HotSpot: http://cr.openjdk.java.net/~ehelin/8004172/hotspot/webrev.00/

Bug:
http://bugs.sun.com/view_bug.do?bug_id=8004172

Testing:
Run the jstat jtreg tests locally on my machine on a repository where 
I've applied both the JDK changes and the HotSpot changes.

Thanks,
Erik
