  Added detection of touch devices before first touch events happen on Android.
  
  On Android available touch devices are now added with video initialization (like
  the keyboard). This fixes SDL_GetNumTouchDevices() returning 0 before any touch
  events happened although there is a touch screen available. The adding of touch
  devices after a touch event was received is still active to allow connecting
  devices later (if this is possible) and to provide a fallback if the new init
  did not work somehow. For the implementation JNI was used and API level 9 is
  required. There seems to be nothing in the Android NDK's input header (input.h)
  to implement everything on C side without communication with Java side.
