Adding support to allow engines to tell what formats they can handle.
The server will generate an error if it is not possible to log the
statement according to the logging mode in effect.

Adding flags to several storage engines to state what they can handle.

Changes to NDB handler removing code that forces row-based mode and
adding flag saying that NDB can only handle row format.

Adding check that binlog flags are only used for real tables that are
opened for writing.


BitKeeper/deleted/.del-binlog_row_blackhole.result:
  Rename: mysql-test/r/binlog_row_blackhole.result -> BitKeeper/deleted/.del-binlog_row_blackhole.result
BitKeeper/deleted/.del-binlog_row_blackhole.test:
  Rename: mysql-test/t/binlog_row_blackhole.test -> BitKeeper/deleted/.del-binlog_row_blackhole.test
mysql-test/t/partition_hash.test:
  Adding error check for statement that might fail.
sql/ha_ndbcluster.cc:
  Removing statements that switch to row-based format.
  Adding row capabilities.
sql/handler.h:
  Adding handler/table flags to indicate that the engine is row- and/or
  statement-logging capable.
  
  Adding typedef for table_flags type.
sql/set_var.cc:

  Binlog flags should only be checked for real tables that are opened for
  writing. Adding code to check that.
