WL#2347 - Load independent heartbeats Reset missed heartbeat count on receipt of signal from node. This fixes a bug where that under high network load, the heartbeat packets could be delayed, causing the appearance of node failure (due to lost heartbeats). ndb/include/kernel/NodeInfo.hpp: Add m_heartbeat_cnt to track missed heartbeats ndb/include/transporter/TransporterCallback.hpp: add prototype for transporter_recv_from() Called on receipt from a node. ndb/src/common/transporter/TransporterRegistry.cpp: Add calls to transporter_receive_from when data is received (before unpack) ndb/src/kernel/blocks/qmgr/Qmgr.hpp: remove NodeRec::alarmCount. missed heartbeat count now kept in NodeInfo ndb/src/kernel/blocks/qmgr/QmgrMain.cpp: Use NodeInfo::m_heartbeat_cnt for missed heartbeat count ndb/src/kernel/vm/TransporterCallback.cpp: add transporter_recv_from(), which is called on receipt of signals. It resets missed heartbeat count for that node. ndb/src/ndbapi/ClusterMgr.cpp: Use NodeInfo::m_heartbeat_cnt for missed heartbeat count ndb/src/ndbapi/ClusterMgr.hpp: Use NodeInfo::m_heartbeat_cnt instead of ClusterMgr::Node::hbSent for missed heartbeat count. We now use the same storage for API and Kernel heartbeats. Add ClusterMgr::hb_received(nodeId) to reset hbSent (as if we received a heartbeat, but callable from elsewhere - e.g. when signal received) ndb/src/ndbapi/TransporterFacade.cpp: Implement transporter_recv_from for ndbapi - which resets hbSent ndb/src/ndbapi/TransporterFacade.hpp: Add hb_received(nodeId)
