In the case of a repeated start, we won't get a STOPF/AF status, but we still need to complete the old transaction before handling ADDR.

Move the DMA start to immediately after setting it up; less latency at interrupt time, and no chance of getting start/stop calls out of sync.

Move DMA start for tx/rx into the gap where SCL is still stretched so that there is no risk of receiving the first byte before DMA starts.

Configure the DMA channels in circular mode so that we don't have to deal with the case where DMA stops but the master is still talking.
Use AF as well as STOPF to decide when transfer has ended. We don't seem to get STOPF when we are transmitting.
