Start of support for older transport and cleanup.
* runtime/transport/control.c: Added inclusion of linux/delay.h to get
declaration of msleep().
* runtime/transport/relay_v2.c: New skeleton file for transport version 2.
* runtime/transport/ring_buffer.c: Cleanup.
* runtime/transport/transport.c: Ditto.
