    libxl: gentypes.py: Break out libxl_C_type_do_init
    
    This is going to be the common way to initialise things.
    _libxl_C_type_init remains the thing for generating the body of the
    init function, and for some special cases.
    
    No functional change with existing types: C output is identical.
