Hmm, dbopen(3) accepts openinfo
argument, which can be used to pass access-method specific data.
We can change it so that if openinfo is specified and file already exists,
lorder (see hash(3)) of passed structure is set to byte order of the db.
Then, we would not need any special entry in the database file to find
out its endianness.
Other possible hack is to add flag R_ENDIANNESS and cause DB->get()
with flag == R_ENDIANNESS to return endianness indication.
