Ruben Perez ac7285c621 server_diagnostics and client/server error categories.
Renamed error_info to server_diagnostics.
server_diagnostics::message is now correctly treated as user-supplied input
  (security fix). Added notes on examples on this.
Split server and client errors in different categories.
Added throw_on_error.
Added connection::rebind_executor.
Made error categories public.
Exception throwing now uses Boost.Exception.
Improved error handling in examples.
Updated Asio dependencies for stackful coroutines.
