without this the magic numbers need to be kept in sync with the maximum length of the strings printed in the corresponding column. if not an overflow and a nasty ' '-storm occurs on executing flashrom -L.

after a short discussion with carldani i have removed the assert stuff and do some inferior array checking in selfcheck. we only have _extern_ references to the tables to sizeof does not work. we could add a "getter" for the sizes of the array or bring the tables into view to improve this... but i dont think it's worth it.
