Add support for pickling enginefacade context objects
In order to pickle a context object which refers
to an active _TransactionContextTLocal, we have to
use __reduce__ so that no database, engine, or session
state is pickled, and only a constructor remains. Upon
unpickling, the constructor will install a new, empty
_TransactionContextTLocal on the new context, as is
appropriate since this is a totally different context object
than the original one.
