the CASETABLE torture target now generates the complete unicode

equivalence table for a server. This was inspired by the chargen win32
code from monyo.

This takes a *long* time to run against a Samba server due to the case
insensitive comparisons in the filesystem. That makes it a N^2
operation, and N is 64k. It is linear on NT.
(This used to be commit 441f9415b365787854fb0d3e04d1ea4938d7af73)
