This series introduces ibv_query_qp_data_in_order() verb.

This verb enables an application to check whether the receiving data of the
local QP is guaranteed to be in order for a given operation within its WQE.

Once true, it allows user to poll for data instead of poll for completion.

The API was implemented by mlx5 driver over DEVX.

A detailed man page and some pyverbs stuff were added as well.
