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
