[10] RFR: 8185796: jstack and clhsdb jstack should show lock objects

[Yasumasa Suenaga]

Thanks Jini!

I uploaded new webrev:

   http://cr.openjdk.java.net/~ysuenaga/JDK-8185796/webrev.01/

This webrev has been ported print_lock_info() to JavaVFrame.java, and I've added new testcase for `jhsdb jstack` and jstack command on `jhsdb clhsdb`.

The target process does not have to be be fixed to LingeredApp -- in these LingeredAppWith* cases, the targets are test-specific variations built on top of LingeredApp for ease of implementation.
