Get rid of pointer warnings in ptp2/library.c's get_file_func function:


 /* Note that "image" points to unsigned chars whereas all the other
  * functions which set image return pointers to chars.
  * However, we calculate a number of unsigned values in this function,
  * so we cannot make it signed either.
  * Therefore, we have a number of casts, which is ok, as the casted
  * pointers are just generic pointers to "data" anyway.
  * If you do not like that, feel free to clean up the datatypes. */
