Input::Binding for non-C++ language bindings

Browse Source 
Quietly insert forward declaration of a Input::Binding class, and make
it a friend of Input::Event and Input::Session_client. This is to allow
non-C++ language bindings (Nim) to access private members by providing
their own implementation of the Binding class.

Fix #2889
