b36b15586a Fix bugs that prevent from using AppFuse. 
* Allow buffer size that is greater than requested read size in JNI,
   because we reuse fixed-size buffer among multiple requests.
 * Fix condition to check if the file size is greater than 4GB or
   not. We need to use 0xffffffffl instead of 0xffffffff because
   0xffffffff is int and its value is -1.
