In preparation for Unicode support for the keyboard layer, we'd better get rid of all the hardcoded 0x100/0xff constants in kbdcontrol. Instead, add a flag called SPECIAL stored in the top bit of the integer. Adding Unicode support is very simple now; just change u_char map[] to u_int map[] in keyent_t, change the bounds checking in kbdcontrol to 0x1FFFFF and modify the ioctls to allow loading these new keymaps.
