revised patches for kerberos vulnerability

[tlyu () MIT EDU (Tom Yu)]

The patches previously posted for fixing the krb4 buffer overruns had
some whitespace issues resulting from untabifying.  Some versions of
patch don't like that.  Use "patch -l" instead, or use the fixed
patches at

        http://web.mit.edu/kerberos/www/advisories/index.html

These fixed patches have tabs repaired and also have pathnames in the
diff headers fixed to include directory names so that they may be
applied from the top of a source treee.
