change from IndexNumber to FileId.
(fhandler_base::fstat_helper): Call hasgood_inode here.
(fhandler_disk_file::opendir): Call fhaccess only for real files.

postprocessing only once.
(readdir_get_ino_by_handle): New static function.
(readdir_get_ino): New function to centralize inode number evaluation
in case inode number hasn't been returned by NtQueryDirectoryFile.
(fhandler_disk_file::readdir): Move old functionality to readdir_9x.
