[Automaton] Make Automaton thread-safe
In an optimization to improve performance (rL375240) we added a std::shared_ptr
around the main table map. This is safe, but we also ended up making the
transcriber object a std::shared_ptr too. This has mutable state, so must be
copied when we copy the Automaton object. This is very cheap; the main optimization
was about the map `M` only.
Reported by Dan Palermo. No test as triggering this is rather hard from a unit test.
