BDB_MULTI still needs the dupsort function.

Use a 4-byte constant for the presence index key. Set the index db hash
...
function to simply pass thru the key value, which is already a hash value.

Use DB_HASH instead of DB_BTREE for index databases. Since index keys are
...
mainly 4-byte hashes already, there is no locality-of-reference to exploit
as a Btree. About a 7% performance gain.

Revert previous checkin, DB_NODUPDATA is not valid on db->set_flags().
...
It must be specified on individual put() operations (and already is).

Experimental index management. Uncomment BDB_IDL_MULTI in back-bdb.h
...
to activate. Needs to check limits in bdb_idl_insert_key, will get to
that later.

Fix, index databases were not being closed on shutdown.

Renamed BDB_ID2ENTRY_PAGESIZE to just BDB_PAGESIZE; set it on each database
...
instead of just the id2entry db. It helps. I also found that tweaking the
environment (set_lg_bsize 2MB; set_cachesize 2MB) helps but those can be
taken care of in a DB_CONFIG file. Tweaked the bdb_bt_compare function; it
really only needs to be set on little-endian machines. (On big-endian machines
a lexical sort gives the same result as an integer sort.) Moved the final
checkpoint back to the dbenv_close, I think this leaves a cleaner log file.

BDB_INDEX code does no harm (but no good yet, not used by filters yet).

Another round. BDB_INDEX almost ready for functional testing.

Add some initial BDB_INDEX code... needs much work.
