Fixed problems found by valgrind 

Fixed problems in test suite where some test failed
Fixed access to not initialized memory in federated
Fixed access to not initialized memory when using BIT fields in internal temporary tables


BitKeeper/etc/ignore:
  added libmysqld/sql_cursor.h
mysql-test/r/information_schema.result:
  Change view names to 'v#' to not cause massive conflict with other tests if test dies in the middlecd
mysql-test/r/information_schema_inno.result:
  Remove used tables at start
mysql-test/r/multi_statement.result:
  Remove used tables at start
mysql-test/r/temp_table.result:
  Change view names to 'v#' to not cause massive conflict with other tests if test dies in the middle
mysql-test/r/type_bit.result:
  More tests
mysql-test/t/information_schema.test:
  Change view names to 'v#' to not cause massive conflict with other tests if test dies in the middle
mysql-test/t/information_schema_inno.test:
  Remove used tables at start
mysql-test/t/multi_statement.test:
  Remove used tables at start
mysql-test/t/temp_table.test:
  Change view names to 'v#' to not cause massive conflict with other tests if test dies in the middle
mysql-test/t/type_bit.test:
  More tests
mysql-test/valgrind.supp:
  Removed some valgrind warnings that isn't errors
sql/ha_federated.cc:
  Fixed errors discovered by valgrind:
  - Socket was not initialized
  - share->scheme was deleted while there was still pointer into it from the hash
sql/item_func.h:
  Remove access to table object from cleanup() as the table object may have been dropped earlier (In case of temporary tables or of close_thread_tables() is run before cleanup())
  This fixed a bug with access to already freed memory
sql/sql_base.cc:
  Reset variables used by fulltext
sql/sql_select.cc:
  Fixed various problems with bit fields when used in internal temporary tables.
  Calculate space needed for bit fields correctly (previously we allocated more space than needed for rows in heap/myisam tables)
