The smb client and server code have (mostly) duplicated code
for unicode manipulation, in particular upper case handling.
Flatten this lot into shared code.
There's some code that's slightly different between the two, and
I've not attempted to share that - this should be strictly a no
behaviour change set.
I'd love to also boil out the same code from fs/jfs/ - but that's
a thought for another time (and harder since there's no good test
for it).
Lightly tested with a module and a monolithic build, and just mounting
itself.

So far so good, but please drop the "cifs_" prefix from this new file's
name, since its contents apply to later smb dialects as well.
