[SPARC64]: Assorted LDC bug cures.
1) LDC_MODE_RELIABLE is deprecated an unused by anything, plus it and LDC_MODE_STREAM were mis-numbered. 2) read_stream() should try to read as much as possible into the per-LDC stream buffer area, so do not trim the read_nonraw() length by the caller's size parameter. 3) Send data ACKs when necessary in read_nonraw(). 4) In read_nonraw() when we get a pure ACK, advance the RX head unconditionally past it. 5) Provide the ACKID field in the ldcdgb() packet dump in read_nonraw(). This helps debugging stream mode LDC channel problems. 6) Decrease verbosity of rx_data_wait() so that it is more useful. A debugging message each loop iteration is too much. 7) In process_data_ack() stop the loop checking when we hit lp->tx_tail not lp->tx_head. 8) Set the seqid field properly in send_data_nack().
