Note also that tds_convert_any check if destlen is -1 or -2 and do
padding/terminating for other conversion.

I don't see also the NULL case. What happen is a string is NULL? It should
have -1 as srclen and give some error copying string...
Also we must fix also conversion from unicode (we always append terminator).

In tds_convert_numeric we do tds_numeric_to_string(src,dest) without
checking if there is enough space on dest (same problem in money
conversion)...
