The problem was that THD::row_count_func was zeroed too. It was zeroed
as a fix for bug 4905 "Stored procedure doesn't clear for "Rows affected"
However, the proper solution is not to zero, because THD::row_count_func has
been set to -1 already in mysql_execute_command(), a later fix, which obsoletes
the incorrect fix of #4095

The code that set up data to be passed to user-defined functions was very
old and analyzed the "Type" of the data that was passed into the UDF, when
it really should analyze the "return_type", which is hard-coded for simple
Items and works correctly for complex ones like functions.

 - Most likely caused by linking with libmysqlclient using gcc and not g++.
 - Removing our "yassl_dummy_link_fix" hacks so some test programs are linked
   with gcc 
 - Remove build of non working test programs in vio

result from "require mysql_upgrade"

in Makefile.am.

- Cleanup the Makefile for client
- Don't link mysqltest with mysys as it's been compiled with different flags.
