Process the BTN_MOUSE event

This is required in order to make the trackball on devices that has it to
work properly, like it does before ICS. In addition to this patch, you just
need an .idc file that matches the device name for your the trackball. You can
find it by either looking in a kernel log or a logcat.

For example, a device with a Crucial optical navigation pad, will be called
curcial-oj.idc

The .idc file should contain the following:

cursor.mode = navigation
cursor.orientationAware = 1

Place the file in /system/usr/idc folder.

Enable in BoardConfig.mk with BOARD_USE_LEGACY_TRACKPAD := true

simplify and improve BOARD_USE_LEGACY_TOUCHSCREEN

in addition to converting ABS_MT_TOUCH_MAJOR to ABS_MT_PRESSURE, it also converts ABS_MT_WIDTH_MAJOR to ABS_MT_TOUCH_MAJOR.

also add 2 workarounds for some touchscreen driver which
 1. has BTN_TOUCH feature but it doesn't send BTN_TOUCH event
 2. sends multi-touch event for not-in-use pointer
