This series from Danit and Yossi enables application control in some flows as
follows.

It exposes the internal function 'rdma_init_qp_attr' as an external librdmacm
API. As such an application can get the parameters for creating AH (needed for
DC QP), or control QP attributes after its creation.

In addition, it exposes CONNECT_RESPONSE event and rdma_establish() API.
Applications which do not create a QP through rdma_create_qp() may want to
postpone the ESTABLISHED event on the passive side, to let the active side
complete an application-specific connection establishment phase. For example,
modify a QP created by the application to RTR, or make some preparations for
receiving messages from the passive side.
