      Description

         This is a breakout from JDK-8293114, which is starved for reviews. So I attempt to break up that fix into smaller units which are hopefully easier to review separately.

        We can trim the C-heap manually using jcmd since JDK-8268893. This patch reforms this API somewhat, cleaning it up in an OS-agnostic way. That will allow us to add implementions for other platforms (I have this on my list for AIX at least).
