d17a0248a2 rdma: Add an option to set net namespace of rdma device 
Enrich rdmatool with an option to set network namespace of RDMA
device. After successful execution of it, rdma device will
be accessible only in assigned network namespace.

rdma tool command examples and output.

First set netns mode to exclusive.

$ rdma system set netns exclusive

Now create network namespace and assign RDMA device to this
network namespace.

$ ip netns add foo
$ rdma dev set mlx5_1 netns foo

8f5cfd23cd rdma: add helper rd_sendrecv_msg() 
This function sends the constructed netlink message and then
receives the response.

Change rd_recv_msg() to display any error messages.

Change 'rdma dev set' to use rd_sendrecv_msg().

f2ffa0a0ff rdma: Update device capabilities flags 
In kernel commit e1d2e8873369 ("IB/core: Add PCI write
end padding flags for WQ and QP"), we introduced new
device capability to advertise PCI write end padding.

PCI write end padding is the device's ability to pad the ending of
incoming packets (scatter) to full cache line such that the last
upstream write generated by an incoming packet will be a full cache
line.

This commit updates RDMAtool to present this field.

8b92a2c930 rdma: Move per-device handler function to generic code 
Most of the proposed objects are working in the scope "dev"
and will implement the same logic. Move the code to utils.c,
so other objects will be able to reuse the code.
