Need approval, JDI updates to openjdk6

OpenJDK6 changes for JDI. I'm ready to push.
I would like approvals from Joe, Jim, Alan, Dan, and Tim.
In the process of trying to get good test results running the openjdk6
debugger (JDI) and jvmti tests (com/sun/jdi and demo/jvmti), I kept running
into fixes made in jdk7 that were not in jdk6.
Since this functionality and apis are still jdk6, I took the liberty
of porting all of the openjdk7 JDI changes and JDI test changes to openjdk6.
These changes have all been reviewed for jdk7, and with a few minor
exceptions (i.e. -target 7 -source -7 in a few places) the resulting
files in openjdk6 now match openjdk7.
Please speak up if you have objections to this.
The openjdk6 com/sun/jdi tests are stable now, however for some reason
I am unable to run them with 'jtreg -samevm', but all indications are
that this is unrelated to the JDI tests themselves (the same tests run
fine with -samevm in openjdk7). The jtreg -samevm runs fail with a jtreg
Error. Error while cleaning up threads after test
and it is unpredictable as to what testcase it will happen with.
I'll investigate this again after the openjdk6 version of hotspot
is updated (I think it has 14.0 right now), I'm suspecting a hotspot fix
in 14.2 regarding threads might solve this (6772683, but that's a guess).
Here is the complete webrev:
One changeset contains several bugs because the changes to the files
overlapped so much. I tried to selectively bring in changesets from jdk7
as I needed them, only realizing toward the end that I really needed all
changesets related to JDI to get it right.
