TDS 5.0 supports parameters in the protocol with TDS_DYNAMIC & Co.  TDS
7.0 goes a completely different route, using extended stored procedures
e.g. sp_executesql.  

We support both, cf. src/dblib/unittests/rpc.c.  Admittedly this is a new
area and we're working with undocumented stuff on the server side.  

Bill Thompson said he's nearly ready with a big functional expansion of
ct-lib, and I'm pretty sure that includes parameter support.
