ab801874f8 attack the biggest stack users:

price we pay in code size increase:

1aa7e477b1 reorganize applet table. Eliminates pointers to names. 
Should be a big win for libbusybox. busybox wins too:

ca525b4f24 *: BB_BANNER -> bb_banner (it is not a const or #define)! 
correct_password: explain in detail why it is ok to use bb_banner
