Hello

Please review these backports of JDK-8209061:Move G1 serviceability functionality to G1MonitoringSupport  and JDK-8209062:Clean up G1MonitoringSupport to jdk11u

These backports are prerequestes for JDK-8207200 which we can see in the wild with jdk8 and jdk11.

JDK-8209061 and JDK-8209062 applies mostly clean, very few places where it wasn’t clean due to surrounding code or code layout.

after these two, JDK-8207200 applies cleanly.

Testing: tier1.

The webrevs:

This looks good to me and matches http://hg.openjdk.java.net/jdk/jdk/rev/ec014e5694ec.

http://cr.openjdk.java.net/~vkempik/8209062/webrev.00/

This looks good to me also and matches http://hg.openjdk.java.net/jdk/jdk/rev/9a5200b84046.
