Some fixes for BDB_IDL_MULTI. Experimental back-hdb code.

Re-introduce BDB_ID2ENTRY_PAGESIZE. Even if the index databases can get
...
by on 4K pages, the id2entry database still needs more (16K).

When using BDB_IDL_MULTI, there are no longer any issues with storing
...
large IDLs. Concurrency is improved by using as small a page size as
possible. So, set the pagesize back to the default 4096 in this case.

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.

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.

Set the id2entry database pagesize to BDB_ID2ENTRY_PAGESIZE to avoid
...
overflow/fragmentation. (This is now 16K vs default 4K.) It turns out
that the entries' on-disk format is quite space-inefficient, storing
4 bytes per pointer or integer when typically >50% of those bytes are
zero. Oh well. It's about a 2:1 space increase over ldbm now, vs 4:1
before when all the entries were overflowing the 4K pages.

Eliminated nextid database. id2entry database is now maintained in numerical
...
order, so the lastid is always the same as the last entry's ID. This is
an incompatible db file change.

Added "dbnotxn" config keyword. If present, back-bdb uses DB_INIT_CDB
...
(Concurrent Data Store mode) instead of DB_INIT_TXN. Faster, but tends
to impede writers.

Removed unused "range" argument from indexing functions. Fixed more
...
bugs in indexing. Uncommented #define to turn on indexing in back-bdb.h.
It looks like it's working.
