RDS: Add GET_MR_FOR_DEST sockopt
RDS currently supports a GET_MR sockopt to establish a memory region (MR) for a chunk of memory. However, the fastreg method ties a MR to a particular destination. The GET_MR_FOR_DEST sockopt allows the remote machine to be specified, and thus support for fastreg (aka FRWRs). Note that this patch does *not* do all of this - it simply implements the new sockopt in terms of the old one, so applications can begin to use the new sockopt in preparation for cutover to FRWRs.
