  1. tds5_process_dyn_result2: Don't trust Sybase w/blob params. 

    As of ASE 16.0, Sybase servers have started allowing dynamic query
(prepared statement) declarations with IMAGE or (N)TEXT parameters.
However, subsequent attempts to instantiate these queries have been failing
with message 3805, "The token datastream length was not correct."  In such
cases, switch on dynamic query emulation (as already needed for older
Sybase versions that immediately reject these declarations) and explicitly
discard column information to avoid misconstruing the status of subsequent
queries that yield no row results.
