- Additional fixes caused by running without anonymous users


mysql-test/r/federated_server.result:
  There are no default server in mysql.servers anymore
  The test will create it's own test servers
mysql-test/r/rpl_read_only.result:
  Update result
mysql-test/r/rpl_row_USER.result:
  Update test result, it basically checks that the values
  return by USER() and CURRENT_USER() are the
  same on master and slave, so it's doing the correct
  thing. Since connection m_1 is logged in as ''@localhost%
  that is what will end up in the log.
mysql-test/t/ndb_multi_row.test:
  Connect as root instead of '' which would pick currently logged in user
mysql-test/t/rpl_read_only.test:
  Add user test with no privs(no anonymous by default anymore)
