(Vnext_selection_coding_system): New variable.

Browse source 
(syms_of_win16select): DEFVAR_LISP it.  No need to staticpro
Vselection_coding_system.
(Fw16_set_clipboard_data): Always convert multibyte strings.  Use
Vnext_selection_coding_system if non-nil.
(Fw16_get_clipboard_data): Always convert a string that includes
non-ASCII characters. Use Vnext_selection_coding_system if
non-nil.
