-Added quote_data and needs_quotes (moved from federated handler.

-New tests and results

logging_ok:
  Logging to logging@openlogging.org accepted
ha_federated.h:
  removed quote_data and type_quote (now in the Field class)
ha_federated.cc:
  moved quote_data and type_quote to field class
field.h:
  new methods quote_data and needs_quotes declared
field.cc:
  new field class methods quote_data and needs_quotes (per Monty's request)
federated.test:
  more tests, joins, index tests
have_federated_db.require:
  new name of federated system var
federated.result:
  new test results for federated handler
have_federated_db.inc:
  changed name of variable in test due to change in vars
sql_analyse.cc:
  over-ridden append_escaped to take (String *, char *, uint) per requirements of 'create_where_from_key' method in federated handler.
mysql_priv.h:
  define over-ridden append_escaped to take arguments from 'create_where_from_key' method in federated handler 
ha_federated.cc:
  implemented "create_where_from_key" to deal properly with two-byte prefix and multi keys. Initial testing shows it works, but I still need to move quoting to field class and also look at changes per Segei's suggestions.
