Make a start on refactoring: work the DB header initialization into its
own function, used from both initTables and batchinsert.

This actually removes a mmap()/munmap() pair from inside the batchinsert
loop over files.  Not really sure why that was there in the first place;
maybe to sync the header to disk more forcefully?  In any case, no
change in behaviour should happen as a result of this code change.

   void pointQuery(const char* dbName, const char* inFile, adb__queryResult *adbQueryResult=0);
   void trackPointQuery(const char* dbName, const char* inFile, adb__queryResult *adbQueryResult=0);
   void trackSequenceQueryNN(const char* dbName, const char* inFile, adb__queryResult *adbQueryResult=0);
   void trackSequenceQueryRad(const char* dbName, const char* inFile, adb__queryResult *adbQueryResult=0);
 
+  void initDBHeader(const char *dbName, bool forWrite);
   void initTables(const char* dbName, bool forWrite, const char* inFile);
   void unitNorm(double* X, unsigned d, unsigned n, double* qNorm);
   void unitNormAndInsertL2(double* X, unsigned dim, unsigned n, unsigned append);
   void insertTimeStamps(unsigned n, ifstream* timesFile, double* timesdata);
   unsigned getKeyPos(char* key);
