- Don't modify the variables which are passed for parameter binding.

  We need to clone them, if there will be a transformation (convert_to_xxx)
  which will change the origin
  (bug#44390 bind_param / bind_result and Object member variables)
- Make mysqlnd more compatible to libmysql, in this case if the execute of
  a statement fails set the state of the statement back to PREPARED
- A test case to check the case of a failing statement.
