Deal with audioDB::UnitNorm

Deal with it by removing it completely, that is.  New inline function
audiodb_l2norm_buffer(), replacing the three instances of that
functionality dotted throughout the code.

 #include "audioDB-internals.h"
 }

   size_t data_buffer_size = ALIGN_PAGE_UP(header->length);
   size_t nvectors = header->length / (sizeof(double) * header->dim);

    * l2norm flag on when we have already inserted a large number of

     goto error;
   }
