To avoid confusion between the heap size (includes header and rounding up) and number-of-elements size or payload size.

- uses thread execution status transition to track when a thread is in a safepoint or needs to block for a safepoint
- introduces a monitor per Thread object
- uses a per thread safepoint handshake between the thread requesting a safepoint and the requested thread.
The ThreadRegistry class now contains only the thread list for an isolate and the functionality of scheduling a thread onto an Isolate and unscheduling it from teh isolate. We could fold this functionality into the Isolate class in a different CL.

Add retaining_path instance command to VM service, exposed in the Observatory
with a [find] eval-link in instance view. By default shows up to 10 elements,
possibly followed by [find more] which doubles the number of elements shown.
Change RetainingPath to include the object itself.
Always include an id in Object::PrintJSONImpl, to avoid instance-ref crashing on
internal objects.

Features:
* Performs a pre-order, depth-first search.
* Allows the visitor to direct whether to
proceed, backtrack, or abort.
* Provides a complete chain of parents to the root.
(unlike the GC marking stack).
The plan is to use this in the observatory, e.g.:
* inspect a path from the isolate roots to a particular object, or
* determine how much memory is kept alive by some particular object or class of objects.
