    sss tools: improve option handling
    
    The crash describe by ticket #2802 is caused by providing NULL options
    in popt and yet trying to iterate over them. Instead of simply testing
    for NULL this patch creates a new option table table merges several
    option tables together, thus improving and simplifying usage string.
