Add support for setting the P_Key index of sent MADs and getting the P_Key index of received MADs. This requires a change to the layout of the ABI structure struct ib_user_mad_hdr, so to avoid breaking compatibility, we default to the old (unchanged) ABI and add a new ioctl IB_USER_MAD_ENABLE_PKEY that allows applications that are aware of the new ABI to opt into using it. We plan on switching to the new ABI by default in a year or so, and this patch adds a warning that is printed when an application uses the old ABI, to push people towards converting to the new ABI.
