Make graph construction work while graph is being concurrently run.
The overall approach is to use Graph._lock to synchronize Session.run calls and construction methods that rely on graph mutation. We don't want to synchronize the actual running of the graph, only the Extend call, so this change exposes an ExtendSession method to the Python API and disables extending automatically in TF_SessionRun.
