Hi all,

I please have reviews and a sponsor for this small change. This is another
breakout from a breakout from 8185034.

In short, this splits the Metaspace class into two classes, one holding the
actual metaspace memory for a single class loader, one serving as a static
namespace for metaspace-central static functions. This dual role made the
code more difficult to read and was a source for errors (see e.g. 8199007).

Bug: https://bugs.openjdk.java.net/browse/JDK-8199431
webrev: http://cr.openjdk.java.net/~stuefe/webrevs/8199431-split-cla

Note: may only apply atop of this patch:  http://cr.openjdk.java.net/~st

Thanks, Thomas
