From 9c5dd7337fa93fb1650cc017e523b939dcbf482a Mon Sep 17 00:00:00 2001

Subject: [PATCH] Let the DDX decide on the XkbRulesDefaults.

Rather than assuming rules in the CoreKeyboardProc, init the default rules in
InitCoreDevices, then re-use them later.

In the xfree86 DDX, set the rules to "base" or "evdev", depending on whether
we'll load kbd or evdev.

If we create a new MD, use pc105,us as default and re-use the rules file used
previously.
