Last weekend I wrote a simple replacement iconv library to meet FreeTDS's
most basic requirements: convert ISO-8859-1 (and 7-bit ASCII) to and from
UCS-2.  It will allow FreeTDS to work as advertized, to connect to any TDS
server without libiconv.  It also means we'll need very few #if HAVE_ICONV
tests in the code, because iconv() will be present in some form.  Whether or
not it's sufficient for the client's purpose becomes a runtime question:
Does it return a valid descriptor for a charset pair?  

CVS code now compiles without linking to an iconv library.  It works with
TDS 5.0 servers.  (!)  

With TDS 7.0, I haven't been able to log in yet.  The problem appears to be
in tds_iconv(), which I had begun to rewrite; I want to make it more similar
to iconv(3) and fix its error handling.  Its current signature is awkward to
use, so I prefer to finish my rewrite first, and then see what's up with my
trivial iconv.  

Frediano:  I had to do something a bit weird with tds_iconv_init().  It was
testing for UTF-8, which my replacement doesn't support.  I changed the
interrogation code to try to convert to ASCII instead, which seems to serve
the same purpose without imposing any arbitrary requirements.
