I think this is a way too aggressive recovery. Your are doing the 9
pulse toggles basically on any error while this is only when the device
keeps SDA low and you want to recover from that. If SDA is not stuck
low, sending a STOP should do. Or do you have a known case where this is
not going to work?

Also, you implement the pulse toggling manually. Can't you just populate
{get|set}_{scl|sda} and use the generic routine we have in the core?
