    tools/ocaml: Build fix following libxl API changes
    
    The following libxl API became asynchronous and gained an additional
    `ao_how' parameter:
        libxl_domain_pause()
        libxl_domain_unpause()
        libxl_send_trigger()
    
    Adapt the ocaml binding.
    
    Build tested only.
    
    Fixes: edaa631ddcee665cdfae1cf6bc7492c791e01ef4
    Fixes: 95627b87c3159928458ee586e8c5c593bdd248d8
