- Move initial NumLock handling from systemd back to kbd:
* Add kbdsettings service written by Thomas Blume (boo#1010880,
kbdsettings, kbdsettings.service, numlockbios.c,
update sysconfig.console and sysconfig.keyboard).
* Exclude numlockbios support for non x86 platforms
(kbdsettings-nox86.patch).
- Drop references to KEYTABLE and COMPOSETABLE (boo#1010880#c32,
boo#1010880#c54, sysconfig.keyboard.del, README.SUSE,
drop kbd.fillup).
- Fix paths in kbd.pl.
