Try to show lock owner in MONITOR thread dump.

A thread in the MONITOR state is blocked waiting on a monitor.  This
raises two interesting questions: (1) what lock is it waiting on, and
(2) who holds that lock?  The answer to (1) can be determined easily by
looking at the source code, but (2) is a bit harder.

This change extracts the target object from the instruction stream and
prints some information about it, e.g.:

- waiting to lock <0x40028c68> (a java.lang.Object) held by threadid=1 (main)

Also: fiddled with "must [not] be locked" on a recently-added function.
