introduce acc per row logical mutex to fix difficult error handling cases
  


storage/ndb/src/kernel/blocks/dbacc/Dbacc.hpp:
  1) Fix per row mutex so that only 1 op at a time is running on a row
  2) Change TUP_ALLOC/DEALLOC semantic, so that a new record will be allocated if LQ = { T1(DEL) - T2(INS) }
  3) Rewrite lock queus to be O(1) in all cases but a few abort cases where we scan parallell queue
  4) Impl. a validate_lock_queue/dump_lock_queue test framework
storage/ndb/src/kernel/blocks/dbacc/DbaccInit.cpp:
  1) Fix per row mutex so that only 1 op at a time is running on a row
  2) Change TUP_ALLOC/DEALLOC semantic, so that a new record will be allocated if LQ = { T1(DEL) - T2(INS) }
  3) Rewrite lock queus to be O(1) in all cases but a few abort cases where we scan parallell queue
  4) Impl. a validate_lock_queue/dump_lock_queue test framework

storage/ndb/src/kernel/blocks/dblqh/Dblqh.hpp:
  1) impl. a new read key from operation record needed by acc
  2) expand TRACE_OP toolkit
  3) impl. ACCKEY_ORD as needed by ACC changes

storage/ndb/src/kernel/blocks/dbtup/Dbtup.hpp:
  remove unused states/methods
storage/ndb/src/kernel/blocks/dbtup/DbtupExecQuery.cpp:
  remove extremly tricky code that handles disk_insert_but_no_mem_insert
    that is no long needed with current acc changes
storage/ndb/src/kernel/blocks/dbtup/DbtupGen.cpp:
  remove unused states/methods
storage/ndb/test/ndbapi/testOperations.cpp:
  renable last 3 lock upgrade testcases since they now pass
