X touchscreen fixes for F18

[Daniel Drake]

Hi Peter,

Would it be OK for me to add the following touchscreen input fixes to
xorg-x11-server in F18 + rawhide?

Sync TouchListener memory allocation with population in TouchSetupListeners()

Xi: Don't check for TOUCH_END, it's never set

At OLPC we have a big focus on touchscreens at the moment and the
above patches are essential.

I'd do all the testing and building and push as far as updates-testing.

Thanks
Daniel
