Subject: client: handle the redundant right ctrl windows' message send when a
 alt-gr is pressed bz#709074

Hello,

I first updated the translate_key function. It now requires the windows
message as parameter (will be used later). It also use the raw wparam
and lparam parameters in order to remove the code duplication when
calling the function.

     Gal.
