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.

Clean up MAP_FAILED handling in mdb.
...
Delay (MDB_txninfo*) cast to after comparing mmap() with MAP_FAILED.
Otherwise, if MAP_FAILED = (void*)-1 but MDB_txninfo requires stricter
alignment, the compiler could assume the result is never MAP_FAILED.
Also store NULL in env->(me_map, me_txns) after mmap failure.
