Subject: [RFA/JVMTI] Better env list locking

Hi,

A long time ago, I noted errors in the environment list locking in jvmti.cc. Well, at long last, the time has come to fix it. With the recent merge, we now have access to ReentrantReadWriteLock, which is what is now used to lock the environment list.

Once again, this patch looks a lot bigger than it is. Much of it just moves some chunks of code around.

Comments/questions/concerns?
