fix scan bugs introduced by acc modifications
  add more error testcases


storage/ndb/src/kernel/blocks/dbacc/Dbacc.hpp:
  remove unused state
storage/ndb/src/kernel/blocks/dbacc/DbaccMain.cpp:
  1) remove unused state
  2) Fix abort of running lock owner
  3) Fix abort of running op in parallell queue (especially scans)
storage/ndb/src/kernel/blocks/dblqh/DblqhMain.cpp:
  remove some printouts
  add some jams
  fix so that close tupscan, can not acciently start acc scan in queue
    (NOTE limits #tupscans to 12 which is not really necessary...but the fix was easy)
storage/ndb/src/kernel/blocks/dbtup/DbtupScan.cpp:
  Use abort of locks when closing/blocked
    as Dbacc gets annoyed when committing an op with state running
storage/ndb/src/kernel/blocks/dbtux/DbtuxScan.cpp:
  Use abort of locks when closing/blocked
    as Dbacc gets annoyed when committing an op with state running
storage/ndb/test/include/HugoOperations.hpp:
  new method
storage/ndb/test/ndbapi/testBasic.cpp:
