Yuji Hagiwara (3):
      fat: Fix incomplete comparing in compare_name and compare_short_name
         compare_name and compare_short_name compare incompletely if the
         argument "name" is shorter than a name of directory entries. This
         causes a failure to load EFI as reported in #164
      loader: fix default_entry_file to include the file extension as well
         default_entry_file() returns only the basename but it doesn't
         return the extension. this becomes problematic after compare_name()
         compare names' length too to fix #164. default_entry_file() seems
         to assume that the extension of the file is ".conf".
      efi: Check if the buffer has enough length in read() of a directory
         first
