The Linux kernel adds a few evdev keycodes roughly every other release. These aren't available as keysyms through XKB until they have been added as keycode in xkeyboard-config and mapped there to a newly defined keysym in the X11 proto headers. In the past, this was done manually, a suitable keysym was picked at random and the mapping updated accordingly. This doesn't scale very well and, given we have a large reserved range for XF86 keysyms anyway, can be done easier. Let's reserve the range 0x10081XXX range for a 1:1 mapping of Linux kernel codes. That's 4095 values, the kernel currently uses only 767 anyway. The lower 3 bytes of keysyms within that range have to match the kernel value to make them easy to add and search for. Nothing in X must care about the actual keysym value anyway. Since we expect this to be parsed by other scripts for automatic updating, the format of those #defines is quite strict. Add a script to generate keycodes as well...
