2181fb4af8 ftpd: new option -a ANON_USER to allow anonymous logins 
Anonymous ftpd login is useful even when ftpd authentication feature
is enabled. Anonymous logins provide simple password-less connection
for FTP clients.

To allow password-less connection user command line option '-a USER' is
added. This option specifies the system user to use when
'anonymous' username is given in USER command. No password is required
in this case.

49ecee098d tls: add 2nd cipher_id, TLS_RSA_WITH_AES_128_CBC_SHA, so far it doesn't work 
Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;)

This change adds inevitable extension to have different sized hashes and AES key sizes.
In libbb, md5_end() and shaX_end() are extended to return result size instead of void -
this helps *a lot* in tls (the cost is ~5 bytes per _end() function).

9a647c326a separate TLS code into a library, use in in wget 
A new applet, ssl_client, is the TLS debug thing now.
It doubles as wget's NOMMU helper.
In MMU mode, wget still forks, but then directly calls TLS code,
without execing.

This can also be applied to sendmail/popmail (SMTPS / SMTP+starttls support)
and nc --ssl (ncat, nmap's nc clone, has such option).
