This allows callers to specify commands that should be run in the background
while running QEMU. This can be specified by assigning the commands to the
'QB_BACKGROUND_COMMAND' varialbe in the machine conf.
This is useful for starting automated debugging instances, automated
testing instances (using QMP) or other servers/clients that QEMU can
connect to.
