Convert KDrive to GPE/GKE interface.
Add first-class drivers and enumerate every device separately through
Xi, instead of lamely attempting to aggregate them.
Add XKB support to the Linux keyboard driver.
Add 'thumb button' support to the tslib driver.
Rejig InitInput, so each DDX has to add a list of drivers it supports.
Support NewInputDeviceRequest, et al.
the server seems to act as before. With RedirectSubwindows (root,
automatic), the server looks just like a regular X server. Now to go
rewrite the (currently lame) compositing manager to get some real
action on the screen.
Some of the fixes here are to make valgrind quiet with various ioctls used
by kdrive/linux.
Also fixed a bug where fbdev initialization was out of order in fbdev.c and
smi.c
