As somebody should have see there were a lot of commits about SQL_C_WCHAR.

Current status is much better:
- odbc_tds2sql is ok in all cases!
- odbc_sql2tds behave much better the only missing conversion is from WCHAR
to fixed type.
There are however a lot of cases to review like binary blobs and some
SQLGetData/SQLPutData issues
