  Utility methods
ndb/include/ndbapi/NdbOperation.hpp:
  Utility methods
ndb/src/ndbapi/NdbConnection.cpp:
  Don't set theReturnStatus all_the_time, but let it be decided on 
  a operation bases
ndb/src/ndbapi/NdbOperationExec.cpp:
  AbortOption
sql/ha_ndbcluster.cc:
  1) removed execute from define_read_attr
  2) let a bunch of methods use define_read_attr
  3) impl. read_multi_range
