This series adds support for CQ notifications through the verbs api
(ibv_req_notify_cq/ibv_get_cq_event).

In order to achieve that, a new event queue (EQ) object is introduced,
which is in charge of reporting completion events to the driver.

In addition, a new CQ doorbell is introduced that is mmapped to the
userspace provider in order to arm the CQ when requested by the user.

PR was sent:
https://github.com/linux-rdma/rdma-core/pull/1044

Thanks,
Gal
