RFR(S/M): 8217659 monitor_logging updates from Async Monitor Deflation project

[Daniel D. Daugherty]

Greetings,

I have a (S)mall/(M)edium patch extracted from the Async Monitor Deflation
project that is ready for code review. I'm calling this a (S)mall/(M)edium
because the logic changes are (S)mall, but the logging code is tedious and
there's a bunch of it in audit_and_print_stats() so (M)edium.

The short version of what this patch is about:

     This sub-task captures updates and additions to the
     baseline monitor logging code.

The details are in the bug report:

     JDK-8217659 monitor_logging updates from Async Monitor Deflation 
project
     https://bugs.openjdk.java.net/browse/JDK-8217659

Here's the webrev:

     http://cr.openjdk.java.net/~dcubed/8217659-webrev/0-for-jdk13/

This patch along with the other two patches for Async Monitor Deflation
project have been through Mach5 
builds-tier1,hs-tier1,jdk-tier1,hs-tier2,hs-tier3
testing and I'm currently running my stress testing kits on my Linux-X64
and Solaris-X64 servers.

I have been actively using this new logging code while debugging my
port of the Async Monitor Deflation project code.

Thanks, in advance, for any questions, comments or suggestions.

Dan
