A 'GI.Gio.Interfaces.Proxy.Proxy' handles connecting to a remote host via a given type of
proxy server. It is implemented by the \'gio-proxy\' extension point.
The extensions are named after their proxy protocol name. As an
example, a SOCKS5 proxy implementation can be retrieved with the
name \'socks5\' using the function
'GI.Gio.Structs.IOExtensionPoint.iOExtensionPointGetExtensionByName'.
