android: lcd_update/_rect() changes
* rename some java methods (to update(), initialize()) * re-create the ByteBuffer object from the framebuffer on every update. This is needed now since 2c71aa9 added the possiblity for lcd_framebuffer to change. * do so, along with the creation of the dirty Rect object, in native code.
