Enable demo mode of netperf, process mixed demo results to drop
unstable factors, only compute the effective demo results when
all the threads work. This would make performance result more
stable.

We start many clients and watch the demo output, if all the threads
really work, then start to record the interrupt/packet number, and
count the cpu usage. After a fixed test time, record the final
interrupt/packet number.

Currently we use '-b' parameter of netperf to test parallel traffic,
client would send many requests at start of _RR tests, but it's not
real parallelism, we want to use demo mode to improve the
stabilization. This patch removes '-b' parameter and uses multiple
threads for TCP_RR testing.

In netperf-2.6.0, we can assign two arguments (local send size &
remote send size) for TCP_MAERTS by '-m $local_send_size,remote_send_size'

Currently we only assigned useless local send size, this patch corrects
the parameters for TCP_MAERTS.

The command output sometimes include the command line itself which will
cause the results get wrong. So just get the last 4 value which should
be the real data we wanted.

Changes from v2:
Make windows could be client or host.
Add host sub parameters.

We have netserver.exe now, so make netserver.exe works in netperf_win.
Also correct remote.wait_for_login.

In some guest the ssh_cmd will return the commmand line in output
too which may cause the problem for find cpu number. So only take
the numbers in the output.

Run netserver in windows guest and the TCP scenarios in localhost.

changes from v1:

In different version mpstat the parameters show in results are
different. Use the name of the parameter to get the index of
CPU use status related parameter from the command output head.
This will avoid the wrong cpu values calculated in hosts with
different mpstat.

If we use virtio-blk, the interrupt name of virtio-nic
will become virtio1-input/output.
In netperf test, we will only have one virtio-nic,
this updated the pattern to make it works all the time.

We execute remote command by ssh in netperf test,
add this option to disabling some stderr message.

eg:
