All helper client code now uses xcb, so calling XSetAuthorization() is no longer needed. This is the last reference to libX11 from helper clients, so linking with x11-xcb and libX11 is no longer required. Also drop (unneeded?) linking with libXau. Also drop installing these prerequistes on AppvVeyor. Also move prototypes for functions in winauth.c from win.h into a new header, winauth.h, and include that where needed.
