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

removed scan keyinfo
ndb/src/kernel/blocks/dblqh/DblqhInit.cpp:
removed scan keyinfo
ndb/src/kernel/blocks/dblqh/DblqhMain.cpp:
