Subject: [PATCH] Add in SunOS 4.1.x compatible mode for UFS

Add in support for SunOS 4.1.x flavor of BSD 4.2 UFS filing system
Macros have been put in to alow suport for the old static table Cylinder Groups
but this implementation does not use them yet.
This also fixes Solaris UFS filing system access by disabling fast symbolic
links as this does not apear to be compatible with Solaris UFS.

Tested by:
   Ppartitioning a new disk using SunOS 4.1.1, creating a UFS filing system on
   one of the partitions and writing some files to the filing system.
   Using Linux-2.6.22 (patched) to read the files and then write a shed load of
   files to the UFS partition.
   Using SunOS 4.1.1 to verify the filing system is OK and to check the files.
The test host is a sun4c SS1 Clone.

The patch has been attached to prevent it getting mangled.

Regards
 	Mark Fortescue.
