ts_open_restricted - use a custom function for opening the touchscreen's input device file

ts_open_restricted()  is  useful if libts should not be run as root. If such a function is implemented by
       the user and assigned to the ts_open_restricted pointer, it will be called by ts_open()  instead  of  the
       open() system call directly.

       It should open the input device at path with flags while user_data is currently unused.
