plugin XEP-0065, XEP-0096: preparation for plugin XEP-0260 implementation: /!\ SI File Transfert (plugin XEP-0096) is temporarily broken /!\ proxy handling is temporarily broken plugin XEP-0096: use of Deferred for plugin XEP-0065 in the same way as for plugin XEP-0047 plugin XEP-0065: - use of Deferred for sessions - plugin IP is a dependency - plugin NAT-PORT is used if available - everything is now automatic, params are disabled for now (may be re-used in the future to force port or proxy) - proxy infos are managed with a namedtuple - connexion candidates are managed with a dedicate class - priorities can be used for candidates, as needed for XEP-0260 - transfer can now be managed in both direction, with client or server - socks5 server is launcher on demand, once for all profiles - helper methods to try and find best candidate - connection test and file transfer are done in 2 times
