    mini-os: support newer xen interface
    
    Mini-OS is currently setting __XEN_INTERFACE_VERSION__ to a rather
    ancient version.
    
    To be able to use a more recent variant garnt_entry_t must be changed
    to grant_entry_v1_t. In balloon.c we omit initializing elements of
    struct xen_memory_reservation with 0 to avoid problems with different
    named structure elements in different Xen interface versions.
