keymap, state: don't assume led index < xkb_keymap_num_leds xkb_keymap_num_leds() returns the number of leds that have any possibility of being set. Even if a led is defined but can not be set in any way, it is not counted. In a few places currently we assume that led indexes are smaller than this number, which is wrong both for the above reason and for the fact that the xkb format actually allows explicitly setting the indicator index, which means that the indexes might be non-consecutive. We don't really have good API to iterate on leds, now, because xkb_keymap_num_leds is pretty useless. To work around that we use sizeof(xkb_led_mask_t) * 8. This makes the "Group 2" led work (try switching to a layout other than the first in test/interactive). Signed-off-by: Ran Benita <ran234@gmail.com>
