pw_transfer: Python client and C++ service fixes

- Client: respect the pending_bytes field from the transfer parameters
  when sending a chunk.
- Client: Notify the server if a timeout occurred so that it can cancel
  the transfer.
- Client: Don't invoke the end_transfer callback when killing all
  transfers due to an error to avoid modifying the transfer dictionary
  while iterating through it.
- Client: Accept string as well as bytes data for write transfers.
- Server: Terminate a transfer if the client sends more data than
  requested.
- Server: Log and clean up if write transfer parameters fail to send.
