Don't use env-private copy of DB root nodes.
...
Just lookup the DB roots as needed. When many DBs are in use,
most of the copies won't be referenced in a given txn, and
there's a bad race condition in the copy routine.

Add MDB_NOMETASYNC env option.
...
Just a trial. This may not make sense if we decide to split the
meta pages into their own separate file, to allow meta traffic to
reside on a separate spindle.

libmdb: Do not use the MDB_txbody.mtb_txnid field.

Get txn->mt_txnid from the meta page instead. Otherwise it
and txn->mt_toggle could become inconsistent, since read-only
txns fetched both from MDB_txbody without mutex proteciton.
