atkbd(4): Fix "hancha" and "han/yong" korean keys handling. 2022-12-24T08:33:27+00:00 Vladimir Kondratyev wulf@FreeBSD.org 2022-07-19T21:06:22+00:00 bc814b75fd767b19293e73549182a6c824349425 The Korean keyboard has two keys, the Korean/Chinese and the Korean/English toggles, that generate scancodes 0xF1 and 0xF2 (respectively) when pressed, and nothing when released. They do not repeat. As Hanyong/Hancha keys are generally greater than 0x80, which is generally considered a release key, add extra preceding press key event to generate press/release pair. Swap Hanyong/Hancha key codes to match reality. (cherry picked from commit 6a26c99f827ffa9da5e23d466eeb17131fc75238)
