Description:
  Hi,
ha_federated.cc contains a lot of the following:
     query.append(FEDERATED_SELECT);
     query.append(FEDERATED_STAR);
     query.append(FEDERATED_FROM);
     query.append(FEDERATED_BTICK);

String::append(const char *s) does strlen() on every call. OTOH,
ha_federated.h defines for every macro, another one with suffix _LEN
which is exactly the length of the string.

How to repeat:
See ha_federated.cc

  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'

Okay to push, although places like append(STRING_WITH_LEN("'")) could be changed to append('\''), using the single-character version of append()
