9731ca7611 password utils: improve --help, make DEFAULT_PASSWD_ALGO visible if CHPASSWD 
Was:
    $ cryptpw --help
    ...
    Print crypt(3) hashed PASSWORD

        -P,--password-fd=N	Read password from fd N
        -m,--method=TYPE	Encryption method
        -S,--salt=SALT

User: "What methods exist? which one os default?"

Now:
    Print crypt(3) hashed PASSWORD

        -P,--password-fd N	Read password from fd N
        -m,--method TYPE	des,md5,sha256/512 (default des)
        -S,--salt SALT

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.
