[XEND][XM] Fixes for xm list output
Do not output image, security if they are empty
Change xm list slightly to be more informative about state.
Add back store_mfn and console_mfn to the SXP so save/restore can work
again.

XendConfig API
XendConfig will try to mirror as closely the Xen API VM Struct
providing a backwards compatibility mode for SXP dumping, loading.
-
-XendConfig is a subclass of the python dict in order to emulate the
-previous behaviour of the XendDomainInfo.info dictionary. However,
-the new dictionary also exposes a set of attributes that implement
-the Xen API VM configuration interface.
-
-Example:
-
->>> cfg = XendConfig(cfg = dict_from_xc_domain_getinfo)
->>> cfg.name_label
-Domain-0
->>> cfg['name']
-Domain-0
->>> cfg.kernel_kernel
-/boot/vmlinuz-xen
->>> cfg.kernel_initrd
-/root/initrd
->>> cfg.kernel_args
-root=/dev/sda1 ro
->>> cfg['image']
-(linux
- (kernel /boot/vmlinuz-xen)
- (ramdisk /root/initrd)
- (root '/dev/sda1 ro'))
->>>
-
-Internally, XendConfig will make sure changes via the old 'dict'
-interface get reflected, if possible, to the attribute store.
-
-It does this by overriding __setitem__, __getitem__, __hasitem__,
-__getattr__, __setattr__, __hasattr__.
-
-What this means is that as code is moved from the SXP interface to
-the Xen API interface, we can spot unported code by tracing calls
-to __getitem__ and __setitem__.
