users of xorg, in particular on FreeBSD 11.3

In order to improve support when using evdev to manage input devices, in 
particular keyboards, we have switched the default in x11/libxkbcommon 
to the evdev instead of the legacy ruleset.  This was done in ports 
r528813 .

On FreeBSD 11.3, the default configuration still requires the legacy 
ruleset.

If you are using FreeBSD 11.3, or if you are using xf86-input-keyboard 
on FreeBSD 12 or later, you need to change the ruleset used by 
x11/libxkbcommon.

If you have issues with your keyboard, most notably arrow keys, and if 
/var/log/Xorg.*.log shows that the "kbd" or "keyboard" driver is being 
used, you need to switch to legacy rules by setting the environment 
variable XKB_DEFAULT_RULES to xorg.

The easiest way to accomplish this is by adding it to your shell startup 
file.

As an example, for users of [t]csh, put
   setenv XKB_DEFAULT_RULES xorg
in ~/.login

For users of bourne type shells (sh, bash, ksh, zsh, ...) instead put
export XKB_DEFAULT_RULES=xorg
in ~/.profile
