This CL adds structures for bookkeeping for dataflow based on the dataflow protocol. It also adds a master and slave-side implementation of a single root-to-tree path in the protocol, which involves SOR=1 (master denoting a slave send operation) and DOC=5 (slave denoting data send operation). CL includes dataflow status typedef, SOR code typedef, DOC/SOR encoding, transmitting and decoding, CTS/data encoding, transmitting and decoding.
