21765fa063 udhcpc: kill undocumented -W, it was a no-op. 
fix option parsing in the case some CONFIG_x are off.
 disable -b on NOMMU, make backgrounding work correctly
 (if a bit differently from MMU case). Previously,
 it wasn't working at all.
 stop using global data for flags in main(), opt
 bitfield works as well.

4ea83bf562 uclibc insists on having 70k static buffer for crypt. 
For bbox it's not acceptable. Roll our own des and md5 crypt
implementation. Against older uclibc:

   text    data     bss     dec     hex filename
 759945     604    6684  767233   bb501 busybox_old
 759766     604    6684  767054   bb44e busybox_unstripped

so, we still save on code size.

54e19da86d correct_password: if password is 'x' or '*' and there is no shadow, use 
fake encrypted password 'aa' (which is guaranteed to fail password check).

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
fsck_minix: make it print bb version, not it's own (outdated/irrelevant) one

5df955fce2 Do not fail password check if shadow password does not exist - 
fall back to ordinary one

Reduced usage of functions returning datain static buffers.

a389651115 Remove bb_strlen() in favor of -fno-builtin-strlen. Saves as many bytes 
as the old optimization did (actually does slightly better under gcc 4.0), and
simplifies the code.
