A few minor cleanups for recent AbortOption behaviour change.

storage/ndb/include/ndbapi/NdbOperation.hpp:
  Add some comments describing the new AbortOption handling.
storage/ndb/ndbapi-examples/ndbapi_simple_index/ndbapi_simple_index.cpp:
  Fix example to work with new AbortOption handling.
storage/ndb/src/ndbapi/NdbOperationDefine.cpp:
  Add forgotten method implementations.
