ndb - wl1760/bug#18216

  add two new start options that will decrease likelyhood of bug#18612
  push cntr-sp2 logic down into qmgr-sp1 to decrease likelyhood of bug#18612


ndb/include/kernel/signaldata/CmRegSignalData.hpp:
  Expand CmRegReq with lots of stuff
ndb/include/mgmapi/ndb_logevent.h:
  Add Start report during sp1
ndb/src/common/debugger/EventLogger.cpp:
  Add Start report during sp1
ndb/src/kernel/blocks/dbdih/DbdihInit.cpp:
  Init cntrref
ndb/src/kernel/blocks/dbdih/DbdihMain.cpp:
  Fix small bugs related to partial initial start
ndb/src/kernel/blocks/ndbcntr/NdbcntrMain.cpp:
  Remove timeouts as they are handled in QMGR nowadays
ndb/src/kernel/blocks/qmgr/Qmgr.hpp:
  Push cntr sp2 logic down to QMGR to prevent the forming of multiple QMGR cluster
    that will lead to start problems (crashes...)
ndb/src/kernel/blocks/qmgr/QmgrInit.cpp:
  Push cntr sp2 logic down to QMGR to prevent the forming of multiple QMGR cluster
    that will lead to start problems (crashes...)
ndb/src/kernel/blocks/qmgr/QmgrMain.cpp:
  Push cntr sp2 logic down to QMGR to prevent the forming of multiple QMGR cluster
    that will lead to start problems (crashes...)
ndb/src/kernel/vm/Configuration.cpp:
  Add new flags
    --initial-start
    --nowait-nodes
