new method to set size of local table data

clearer configure description texts
changed Ndb_local_table_info to use create, destroy metods and hidden constructor/destructor
move definition if Thd_ndb to .h file and changes seize/release to operate on Thd_ndb instead of Ndb objects
moved allocation/deletion of Ndb objects to Thd_ndb
