That commit broke bsp/stm3210x. The cause is that we calls rtgui_system_init in rtgui_startup. But the calibration starts before rtgui_startup and rtgui_system_init. This lead to crash.

One way to deal with it is move rtgui_system_init out of rtgui_startup and call it manually. But it will affect other bsps. So just revert the "bad" commit.

If we do not calibrate the touch screen, GUI is unusable. This patch use a semaphore to block GUI thread until calibration finish.

Check whether finger is still on the screen. If not, we couldn't determine where the user has touched. It's better to return early rather than give garbage values.

A more sensitive solution might be caculate the position once the interrupt occured. But it's not anti-shake friendly.

The old code only checks touch->max_x > touch->min_x but not touch->max_x == touch->min_x. Thus may lead to divided by zero error.
