Various fixes for JDWP.

- Moved lock of thread list lock into DecodeThread from its callers
- Fixed scope of various locks to prevent locking violations
- Added transition for current thread from runnable to suspended before
  suspending vm, and then a transition back
- Reworked lock ordering to allow JDWP locks to be held while grabbing
  the thread list lock
- Moved debugger PostException until after suspension is re-allowed
