pipe: merge anon_pipe_buf*_ops
All the op vectors are exactly the same, they are just used to encode
packet or nomerge behavior. There already is a flag for the packet
behavior, so just add a new one to allow for merging. Inverting it vs
the previous nomerge special casing actually allows for much nicer code.
