Bug#20942 ha_federated uses String::append(const char *s), strlen() on every call

 - Remove the defines for strings and uses STRING_WITH_LEN directly when calling 'append'


sql/ha_federated.cc:
  Remove the defines for strings and their lengths and use STRING_WITH_LEN directly when calling append().
sql/ha_federated.h:
  Remove the defines for strings and their lengths and use STRING_WITH_LEN directly when calling append().
