Device model cleanup.
- Single config file for xen and device models
(Shell script doesn''t source xmdefconfig anymore)
- No more device-model shell script by default. You can
have one if needed (qemu-dm.debug)
- All logic in the script device-model is moved to python
- $DISPLAY is passed from xm to xend
- Don''t fork vncviewer on dryruns
- Add support for killing device models on domain destroy
- info vmxiopage command added to the monitor
- Refactor shared io page into global and per vcpu state
- Remove the hard coding of IOPACKET_PORT
- move the virtual_platform_def up to domain struct from vcpu
- xm create -n:
