clients: use rdp scancode definitions when sending key events

Browse Source 
This also introduces a slightly more high-level convenience function for
sending key events. The existing function where an RDP protocol flag field has
to be encoded by the caller is very lowlevel ... and a bad fit for fastpath
input. That could use a refactoring.
