User event.
This event is a bit special as it is created by a call to clCreateUserEvent() and doesn't belong to an event queue. Thus, a mean had to be found for all to work.
The solution is the addDependentCommandQueue() function, called every time the user event is added to a command queue. When this event becomes completed, flushQueues() is called to allow all the Coal::CommandQueue objects containing this event to push more events on their device.
This way, command queues are not blocked by user events.
