- got rid of unneded calls to OCIAttrGet when reexecuting the same query

- only invalidate the define list after all rows from a REFCORSOR are read,
  "normal" corsors will now remember their column defines. this means that
  ocigetcolumn[name|type|..] will from now on work even after the result set
  has been read.
