Simplify node attachment APIs.

Browse Source 
With this change, attachment and detachment of a node's output bus is
now consistent:

  * ma_node_attach_output_bus()
  * ma_node_detach_output_bus()

The old function that allowed you to attach the other way around has
been removed as the caller can easily do that themselves by swapping
the order of parameters.
