  The tdb_fetch, tdb_firstkey and tdb_nextkey functions need to take a TDB_DATA
  pointer and return an error code.
  It is also simpler to have tdb_nextkey replace its key argument in place,
  freeing up any old .dptr.

 Internal locking is required to make sure that fcntl locks do not overlap
  between threads, and also that the global list of tdbs is maintained.
