- moved some of the base tests into torture/basic/

- added a CHARSET set of tests, which determines how the server deals
with some specific charset issues related to UTF-16
support. Interestingly, Samba3 already passes all but one of these
tests, because our incorrect UCS-2 and UTF-8 implementations where we
don't check the validity of characters actually matches what Windows
does! This means that adding UTF-16 support to Samba is going to be
_much_ easier than we expected.
