- Add user specified context to all uCM events. Users will not retrieve
any events associated with the context after destroying the corresponding
cm_id.
- Provide the ib_cm_init_qp_attr() call to userspace clients of the CM.
This call may be used to set QP attributes properly before modifying the QP.
- Fixes some error handling synchonization and cleanup issues.
- Performs some minor code cleanup.
