Fix memory leak
BitKeeper/deleted/.del-NdbScanReceiver.hpp~5c295814a47e7bb4: Delete: ndb/src/ndbapi/NdbScanReceiver.hpp BitKeeper/deleted/.del-NdbScanReceiver.cpp~b8a7472e4a7c424f: Delete: ndb/src/ndbapi/NdbScanReceiver.cpp ndb/include/ndb_global.h: Added ndb_end (corresponding to ndb_init) ndb/src/common/util/ndb_init.c: Added ndb_end (corresponding to ndb_init) ndb/src/ndbapi/NdbScanOperation.cpp: Release SCAN_TABREQ and make sure to call NdbOperation::release (that releases other stuff) ndb/src/ndbapi/Ndbinit.cpp: Reorder free-ing so that signal are release last (so that operations holding signals can release the first)
