Hello all!

here are patches to add support for reading CMS EDF filesystems.  CMS is a
single user operating system that is part of IBM's z/VM.  Even the tiniest
of z/VM installations will have a bunch of minidisks formated with this
filesystem.  Think of it as the VFAT of s390 (in terms of popularity).

These patches are loosly based on cmsfs from 2.4.12-ac6.

NOTE:
I decided to send out these patches now even though they're not complete at
the moment.  I plan to expand this description, expand the documentation,
and bunch of other things.

TODO list at the moment:
 - file data translation (EBCDIC to ASCII)
 - support for RECFM=V files
 - better documentation
 - cleanup the code
 - ...and whatever else comes up

Josef 'Jeff' Sipek.
