[PATCH] NLS: Allow user to select 1:1 mapping

[Petr Vandrovec]

Hi Linus,
   patch below allows user to select 'default' encoding,
which has defined mapping for each of 255 byte values, so
one can use it as a fallback when it finds filesystem
with unknown encoding (EBCDIC for example) just to get
characters through filesystem.
