Subject: [Qemu-devel] AltGr and dead keys with VNC

In VNC mode, my AltGr key (mapped to ISO_Level3_Shift) and the dead keys
aren't supported. This patch adds XK_ISO_Level3_Shift (keysym 0xfe03) to
the keymap. Furthermore, it adds support for the dead keys, which were
for some reason present in the keymaps, but not in vnc_keysym.h. This is
relevant for VNC viewers that pass dead keys on to the guest system
(e.g. tightvnc does) and don't compose the accented letters themselves.
