Subject: made secret_t non-constant size and added params_t::query_string function

1. removed checking that secret_t is exactly 20 bytes, because its size is not
   so constant anymore.
2. added a query_string function that produces a query string suitable for use
   in GET and POST requests. I'm making use of it when performing direct
   request when establishing associations.
