Our current fnmatch() code goes to great lengths to use unicode -
however, the way the strings are copied into it, it really is just 'skip
every second character' unicode.  There is no actual conversion being
done, and the result for some unix charsets must be disgusting!

Furthermore, the old codes makes a unicode conversion - but only for the
purpose of strupper_m(), and throws that away again.

The idea of this patch is to do one unicode conversion per string, and
to do the case-insensitive stuff in the actual fnmatch internals, where
we can do it in the comparison, rather than over the entire string.

In testing this patch however, I noticed that our mangling code was
refusing to allow filenames that end in '.'   This caused us to fail our
own tests (or the Samba 2.2 tests actually).

So, I tested Win2k - and it allows filenames to end in .  (as in
'foo.'), so I've removed this part of the code.

With the change to the mangling system, this patch passes Samba 2.2's
masktest, and the push_ucs2 stuff is already applied.

These changes have been applied.
