    tools/libxl: Drop xc_domain_configuration_t from libxl__domain_build_state
   
    The data it stores is initialised and exclusively used within
    libxl__domain_make(), with the important details written back elsewhere by
    libxl__arch_domain_save_config().  Prepare xc_config on libxl__domain_make()'s
    stack, and drop the parameter.
