- rewrite clean_away_stray_files() to use find_files() direct rather than going via make_db_list().
- The only difference between make_db_list() and find_files() is that the information_schema database is not
  return in the list of databases. But it's currently not possible  to create a NDB table in information_schema
  and thus there can not be any "stray" tables there either.
 - testcase added to ndb_reconnect which shows access denied when trying to create table
   in information_schema
 - This avoids patching the MySQL Server to make the static make_db_list() function available
   to use in ha_ndbcluster_binlog and thus the MCP for make_db_list() and LOOKUP_FIELD_VALUES
  can be removed.
- Also remove the NDB_WITHOUT_MAKE_DB_LIST which was used for compiling ndbcluster in MySQL Server
