This adds support for vDAG reading/writing. The stream is opened in reverse mode when trying to TX on a RX stream of when trying to RX on a TX stream, this is a requirement when using a vDAG.
Replaces dag_tx_stream_commit_bytes64() with dag_tx_stream_commit_records64(). Both behave the same when writing to a DAG device but dag_tx_stream_commit_records64() I could only get dag_tx_stream_commit_records64() working when using a vDAG.
