+ * VM I/O related things:
+ - Ignored parameter of vm_create: core_nb, disk_path and disk_size.
+ - Unimplemented save/restore methods
+ * MSG_as_router_get_property_value() was redundent with
+ MSG_environment_as_get_property_value().
+ - Removed MSG_as_router_*propert*() functions
+ - Added MSG_environment_as_set_property_value() for consistency
+ * xbt heterogeneous dictionnaries (created with xbt_dict_new()).
+ Well, they are still there for now, but deprecated with a warning.
+ Please switch to xbt_dict_new_homogeneous() before this is removed
+ for real.
