Variable-size databases, step 1: introduce dbSize field into the
database header.

(Preserve backward-compatibility by assuming that dbSize == 0 implies
dbSize = O2_DEFAULTDBSIZE)

   // FIXME: these lengths and offsets should be size_t or off_t, but
   // that causes this header (and hence audioDB files) to be
   // unportable between 32 and 64-bit architectures.  Making them
   // uint32_t isn't the real answer, as it means we won't be able to
   // scale to really large collections easily but it works around the
-  // problem.  -- CSR, 2007-10-05
+  // problem.  Expanding to 64 bits will of course need a change in
+  // file format version.  -- CSR, 2007-10-05
