Title:  #2778 - make thread names unique (or at least more so)

The real fix as applied to 2.1 and forward is not binary compatible; the
closest I could figure out was to seed the thread counter of the factory
such that each factory copy gets its own start value (using a global);
this solves it for the packaged dispatchers, which either reuse a thread
pool for a whole group of actors (Dispatcher, BalancingDispatcher) or
create only a single thread (PinnedDispatcher).
