First step for WL 2025

Browse Source 
Not yet fully working
Scan reads work fine, not scan updates


ndb/include/kernel/ndb_limits.h:
  Introducing a new parameter plus increasing the max no of parallel
  operations per scan in LQH, first step in WL 2025
ndb/include/kernel/signaldata/ScanFrag.hpp:
  Only need one clientOpPtr
  Concurrency is batch_size to use in this scan
  batch_byte_size is max no of bytes sent in a batch
  first_batch_size is the batch size in the first batch
ndb/include/kernel/signaldata/ScanTab.hpp:
  apiOperationPtr is sent as long signal data
  batch_byte_size and first_batch_size is needed for further transport
  to LQH
  batch size can now be bigger than before
ndb/include/kernel/signaldata/TcKeyReq.hpp:
  More concurrency means more size for scanInfo also in TCKEYREQ
ndb/include/ndbapi/NdbReceiver.hpp:
  New subroutine to caclculate batch size and similar parameters
ndb/include/ndbapi/NdbScanOperation.hpp:
  batch size calculated before sending, not necessary to store anymore
ndb/src/common/debugger/signaldata/ScanTab.cpp:
  Updated signal printer for SCAN_TABREQ
ndb/src/kernel/blocks/backup/Backup.cpp:
  Fixes to make it compile, not fixed for BACKUP being useful yet
ndb/src/kernel/blocks/dblqh/Dblqh.hpp:
  Removed parameters no longer needed and added some new ones.
ndb/src/kernel/blocks/dblqh/DblqhMain.cpp:
  Fix for cmaxAccOps that was using the wrong constant
  Removed old code
  New SCAN_FRAGREQ signal
ndb/src/kernel/blocks/dbtc/Dbtc.hpp:
  New variables
  Removed dead code
ndb/src/kernel/blocks/dbtc/DbtcMain.cpp:
  New SCAN_TABREQ, SCAN_FRAGREQ, SCAN_FRAGCONF and SCAN_TABCONF
  Fixed some error handling to be more efficient
ndb/src/kernel/blocks/suma/Suma.cpp:
  Fixes to make it compile, not yet usable for SUMA features
ndb/src/kernel/vm/Configuration.cpp:
  Fix for wrong constant
ndb/src/ndbapi/NdbApiSignal.cpp:
  Fix for not using constants
ndb/src/ndbapi/NdbApiSignal.hpp:
  Added possibility to get signal sending node from signal
ndb/src/ndbapi/NdbConnectionScan.cpp:
  Moved declaration
ndb/src/ndbapi/NdbReceiver.cpp:
  New routine to calculate batch_size etc.
ndb/src/ndbapi/NdbScanOperation.cpp:
  Various fixes for sending SCAN_TABREQ and other stuff
