engine: graph: Split SendRecv off from the engine

Browse Source 
It can be used in more places if it's not tied to the engine struct.
This also changes the signature so that more information is returned.
This can be used for logging or other useful things. Of note, this
happens to be the same struct as already exists. It's used for
convenience since it happens to match up! Of course they're related.
