Subject: [menu] Add menu commands

Allow iPXE scripts to create menus.  For example:

    #!ipxe

    menu iSCSI boot demonstration
    item install         Install Fedora to ${root-path}
    item --default boot  Boot from ${root-path}
    item shell           Enter iPXE shell
    item exit            Exit to BIOS
    choose label && goto ${label}

    :boot
    sanboot ${root-path}

    :install
    sanhook ${root-path}
    chain http://${next-server}/fedora.ipxe

    :shell
    shell

    :exit
