xen: Introduce VGA sync dirty bitmap support

Browse source 
This patch introduces phys memory client for Xen.

Only sync dirty_bitmap and set_memory are actually implemented.
migration_log will stay empty for the moment.

Xen can only log one range for bit change, so only the range in the
first call will be synced.
