Title: Minor improvement to copas.step()

Very minor update to step() function, to return a result based upon data handled or timeout. Fully transparent, no breaking of existing code.
This tells the caller that it should asap resume IO (eg. next call to step()) because data is coming in, or alternatively it timed out and there is (some) time to do something else temporarily.
