Hellmuth Michaelis b5dd89c336 remove redundant definitions of card types:
- remove all occurances of FLAG_XXX values and replace with CARD_TYPEP_XXX
 - remove sc_flag from isic softc and replace it with sc_cardtyp
remove some left over redundant definitions from isic and i4b_l1.h
remove left over cvs id from i4b cvs repository
