correct NAND/NOR scan operations, and add a test case for it.

ndb/src/ndbapi/NdbScanFilter.cpp:
  translate NAND/NOR into AND/OR, since AND/OR operations are all correct
ndb/test/include/NDBT_Test.hpp:
  add a new method executeOneCtx() in class NDBT_TestSuite, declare it
ndb/test/ndbapi/Makefile.am:
  Add a new test case: testScanFIlter.cpp to test/ndbapi/,
  thus modify the Makefile.am related to it
ndb/test/src/NDBT_Test.cpp:
  add a new method in class NDBT_TestSuite in order to adapt to 
  some customized test cases, because the default NDBT's test talbes
  and flow are fixed, if just modify related existing methods, it will
  influence other test cases in test/ndbapi/
ndb/test/ndbapi/testScanFilter.cpp:
  It's a test case for ndbapi scan filter, test for AND/OR/NAND/NOR scan operations.
