[WIP v2 0/1] Add Qemu Monitor Support

["Saul Wold" <Saul.Wold@windriver.com>]

Version 2!

I figured out that I was saving the monitor_dumper in the wrong
class, so moved where it's saved into the OESSHTarget code, it still
needs to be created in the OEQemuTarget since that's where the runner
is available.

Currently we interact with the JSON (which is new to me) interface of
qmp and right now the write/read is just raw with no JSON dump, that
might be why I am seeing the erros after the first one.  I did try an
empty run_monitor("") between commands, but that did not help. The 
run_monitor() may need to be reworked to deal with JSON.

Also, I still have the static port of 4444 for the telnet/cli version 
of the monitor and the possible race for the generated port as I have 
not found a solution for that yet.

Sau!

The output goes into files as follows:
