Log the output of the command as it runs not when it finished, else
tail -f tmp/work/minnow-poky-linux/core-image-sato/1.0-r0/testimage/ssh_target_log
isn't as useful as it could be.

Split the class in two, one to handle the process and the
timeout based on output and one for the actual ssh/scp commands.
The ssh/scp methods now use the same run method.
It does the same thing as before but:
- it looks cleaner.
- adds support for using a different user than root
- optionally, raises an exception when exit code != 0
(that's useful for code outside of tests, where you wouldn't want
to check the return code every time as the tests do)

Add an optional parameter to SSHControl so the user can specify
and alternate port to the default (22).

Ocasionally AB shows odd false fails like:
http://autobuilder.yoctoproject.org/main/builders/nightly-arm/builds/1/steps/Running%20Sanity%20Tests/logs/stdio
This should fix that by checking for eof instead of
polling the return code of the ssh process, because the process
might still be there.

This patch makes the necessary changes for using the targetcontrol.py module
so that one can run the same tests on a qemu instance or a remote machine
based on the value of TEST_TARGET variable: "qemu" or "simpleremote".
The default value is "qemu" which starts a qemu instance and it's the
with what we currently have.

With "simpleremote", the remote machine must be up with network and ssh
and you need to set TEST_TARGET_IP with the IP address of the remote machine
(it can still be a qemu instance that was manually started).

Basically testimage.bbclass now does something along the lines of:
 - load tests -> deploy (prepare) / start target -> run tests.
There were a couple of changes necessary for tests and
also some cleanups/renames that were needed to adjust this change. (use
ip everywhere when refering to target and server_ip when refering to host/build machine)
Also two unnecessary and unsed methods were dropped from sshcontrol.

Instead of running the commands with a fixed timeout,
we should kill the command if there is no output
for timeout seconds.
Also changed some strings/comments.

It might be useful for debugging to have in the ssh log
the number of seconds a command has run.

Add ssh_options to be used, the same, by ssh and scp:
Decrease LogLevel to ERROR, to suppress warnings (e.g. ssh host
verifications, two warnings in case of having openssh with hpn patches);
We no longer presume that the first line is a warning.

Increase a bit the timeout for ssh commands and also
write in the output that the command timed out (it's
easier to see that in a test fail than checking the ssh log)

Adds some comments to testimage.bbclass and the files it calls,
just to give an ideea of what it does.
