Browse Source 
1) removed acc keyinfo
2) introduce handling of multiple bounds


ndb/include/kernel/signaldata/AccScan.hpp:
  Removed keyinfo from AccScan
ndb/include/kernel/signaldata/TuxBound.hpp:
  Add data word
ndb/include/ndbapi/NdbIndexScanOperation.hpp:
  Added new_bound call, which is used when batching range scans
ndb/src/kernel/blocks/dbacc/DbaccMain.cpp:
  removed keyinfo from acc scan
ndb/src/kernel/blocks/dblqh/Dblqh.hpp:
  removed scan keyinfo
ndb/src/kernel/blocks/dblqh/DblqhInit.cpp:
  removed scan keyinfo
ndb/src/kernel/blocks/dblqh/DblqhMain.cpp:
  1) removed add scan,
     let LQH read keyinfo from tup instead
  2) introduce copy_bounds which handles multiple bounds
ndb/src/kernel/blocks/dbtux/Dbtux.hpp:
  removed scan keyinfo
ndb/src/kernel/blocks/dbtux/DbtuxDebug.cpp:
  removed scan keyinfo
ndb/src/kernel/blocks/dbtux/DbtuxScan.cpp:
