RDMA/uverbs: Export ib_open_qp() capability to user space
Allow processes that share the same XRC domain to open an existing shareable QP. This permits those processes to receive events on the shared QP and transfer ownership, so that any process may modify the QP. The latter allows the creating process to exit, while a remaining process can still transition it for path migration purposes.
