Summary:
We currently give sonar one event base from java / obj-c code to use for scheduling tasks.
This causes a problem, because we schedule reconnect tasks on the event base, and then these tasks interact with rsocket which schedules it's own tasks.
The problem is that we're passing rsocket the same event base. So the reconnect code executes and blocks waiting for rsocket to connect.
But rsocket can never connect because it never executes because that thread is blocked, so we get deadlock.
This is the first step which just changes the interface to pass two event bases.
The consumers will be changed to pass in different threads next.
