use reverse string keys
use sorted duplicates
numeric keys in native byte order: either unsigned int or size_t. The keys must all be of the same size.
with MDB_DUPSORT, sorted dup items have fixed size
with MDB_DUPSORT, dups are MDB_INTEGERKEY-style integers
with MDB_DUPSORT, use reverse string dups
create DB if not already existing
