API: Improve glue mid-layer of the API demo application.
- Extend ub_dev_read() and ub_dev_recv() so they return the length actually
read, which allows for better control and error handling (this introduces
additional error code API_ESYSC returned by the glue mid-layer).
- Clean up definitions naming and usage.
- Other minor cosmetics.
Note these changes do not touch the API proper, so the interface between
U-Boot and standalone applications remains unchanged.
