bug#9757 - ndb

  Impl. stupid mgm lock against shutting down 2 nodes simultaniously
  Add some more dump


ndb/src/kernel/blocks/dbdih/DbdihMain.cpp:
  Impl. 2 new dump 
  1) to query nf handling state
  2) that impl. sending of arbitrary signal...
     to be used with extreme care
ndb/src/kernel/main.cpp:
  enable critical and warnings in out file
ndb/src/mgmsrv/MgmtSrvr.cpp:
  call handleStopReply on nfCompleteRep instead
ndb/src/mgmsrv/MgmtSrvr.hpp:
  call handleStopReply on nfCompleteRep instead
