Fixed bug #68964 Allowed memory size exhausted with odbc_exec

This is done in two steps:

- the ODBCVER has to be rased to 0x0300 which corresponds to Sql
  Server 9, otherwise the client will not recognize several SQL
  datatypes

- additionally the config scripts was tweaked so then ODBCVER
  can be overridden, that still allows enabling compatibility
  with lower versions

Bug #67437 might be fixed by this as well.
