* A long overdue update of xkb-data from v2-23 (2018-04) to v2-35 (2022-04)
* This is the most current xkb-data package version in use by Debian (Sid)
* One later commit (2022-07) fixing the latam locale was cherry-picked
* Some users felt that the unchanged xkb-data files were better named 'orig' than 'bak'.
* Since I'm a maniac, that made me change the 'mod' dir to 'xmod' too.
* Note that you may create a patch with the orig and xmod dirs, if you wish.
