Create and status of huge databases works.

dump also works, but is as yet untested beyond the 4GB limit.

   // 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.  Expanding to 64 bits will of course need a change in
   // file format version.  -- CSR, 2007-10-05
