  Log:
    file: File#truncate and File.truncate release GVL
    
    Like IO#write and IO.open, these file operations have
    unpredictable performance on slow file systems.  Allow other
    threads of the VM to proceed while they are taking place.
    
    * file.c (nogvl_truncate): extract from rb_file_s_truncate
      (rb_file_s_truncate): release GVL
      (nogvl_ftruncate): extract from rb_file_truncate
      (rb_file_truncate): release GVL
