QMP: Introduce qmp-shell
This is a very simple shell written in Python for demonstration purposes. Unfortunately it's a bit awkward right now, as the user has to specify the arguments names and the printed data can be a raw dictionary or list, like the following example: (QEMU) pci_add pci_addr=auto type=nic {u'slot': 5, u'bus': 0, u'domain': 0, u'function': 0} (QEMU) It's worth to note that the shell is broken into two files. One is the shell itself, the other is the QMP class which handles the communication with QEMU.
