touchui: support XInput2 multitouch
Use XI2 multitouch events instead of mouse events as touch event input for touchui build.
Note: XI MT will be supported in X server 1.12 and XI2.2. Please use build switch "use_xi2_mt=<minor version number>" to specify the minimum XI2 minor version. It is useful to test on experimental XI2.1 with MT support (e.g. build with use_xi2_mt=1).
BUG=95150
TEST=(1) build with touchui=1 use_xi2_mt=1 (2) test on ubuntu 11.04 (X server 1.10 and XI2.1 with experimental MT support). (3) manually test if touch works on browser UI and JS touch events.
