Generate the big keycodes table for virkeys.
It read keymaps.csv from stdin and put the generated code to stdout.
Please keep keymaps.csv be exactly the same as:
http://git.gnome.org/browse/gtk-vnc/plain/src/keymaps.csv.
If anything inconsistent happens, please change this file
instead of keymaps.csv which is a mirror.
