After each call to an option function, there should happen:
Xorriso_eval_problem_status()
One should follow its eventual advice to abort.
Options with a varying number of arguments get them passed like
Xorriso_interpreter(). E.g.:
int Xorriso_option_add(struct XorrisO *xorriso, int argc, char **argv,
int *idx, int flag);
They begin to read the arguments at position *idx and will see the list
end either at the next argv which contains the -list_delimiter text or
at argv[argc-1]. After the call, *idx will be the index of the first not
yet interpreted argv.
