added: possibility to ban if a session cookie is incorrect (when we are using encoded cookies)

Browse Source 
added:   possibility to ban if a client tries to hijack the session cookie
added:   possibility to ban if a client did not send a session cookie
renamed: ezc functions:
         login_cannot_login -> ipban_is_login_allowed_from_this_ip  (and the return value was changed)
         login_when_available_login -> ipban_current_ip_expires_time
added: config options:
       // after how many broken encoded cookie we should ban the current IP
       // default: 2 (value in the range <0 - 65535>)
       size_t broken_encoded_cookie_treshold;

       // after how many incorrect session identifiers (or session indices) we should ban the current IP
       // do not set this value too low, as people connecting from the same IP address (from behind a NAT)
       // would be banned if they have an old session cookie remembered in the browser
       // default: 128 (value in the range <0 - 65535>)
       size_t session_hijacking_treshold;

       // after how many times a client will be banned if it did not send a session cookie
       // default: 1000 (value in the range <0 - 65535>)
       size_t no_session_cookie_treshold;
