Invert audioDB::l2norm / audiodb_l2norm()

We now have some functions that shouldn't be exported to the user of the
library, but are used in more than one source file; case in point:
audiodb_sync_header().  Make a new audioDB-internals.h file for them,
and while we're at it put the scary mmap()-related macros in there too.

We can't delete audioDB::unitNormAndInsertL2() quite yet, because it's
used in insertion too, but we can delete the non-append branches.
That's not very much code to lose, but every little helps.

 
   insert_data_vectors(insertoffset, indata + sizeof(int), statbuf.st_size - sizeof(int));
   
   // Norm the vectors on input if the database is already L2 normed
   if(dbH->flags & O2_FLAG_L2NORM)
-    unitNormAndInsertL2((double *)(indata + sizeof(int)), dbH->dim, numVectors, 1); // append
+    unitNormAndInsertL2((double *)(indata + sizeof(int)), dbH->dim, numVectors);
 
   // Report status
   status(dbName);
   VERB_LOG(0, "%s %s %u vectors %jd bytes.\n", COM_INSERT, dbName, numVectors, (intmax_t) (statbuf.st_size - sizeof(int)));
