This patch introduces convenient command-line options -xkb-rules,
-xkb-model, -xkb-layout, -xkb-variant, and -xkb-options, to set default
values for these properties.
These options can be handful for cases in which compile-time default
values don't match user locale, since kdrive doesn't support InputClass
matching rules yet and not all Linux distros provide default rules to
store these values in udev properties (which by the way is a discouraged
practice).
