c616689d9a Cleanup MDB_env.me_txn0.

c0170bc0ec Copy some env flags to txn. Factor out flags. 
Taken from mdb_txn_begin(,,MDB_NOMETASYNC, MDB_NOSYNC,,)
without adding those two flags yet, to align with mdb.master:
Part of 54516639ac (Renumber...)
+ 8adee9464f (Fix per-txn...).

aa10c98f3f For ITS#7789: Ensure mapsize >= pages in use. 
Check new mapsizes against mm_last_pg.  Move
mdb_env_init_meta0() so it can set mm_last_pg earlier.

24add6589b ITS#7771 fix cursor tracking on fake pages 
node_del shifts nodes around, cursors pointing at fake pages
need to have their mc_pg[0] corrected.

9ed1e57440 ITS#8264 fix cursor_del cursor tracking 
Some destination fixups need to happen immediately after nodes
are moved, before rebalancing

8bdadf68c5 ITS#8258 fix rebalance/split 
The tree height can also increase during rebalance, not just shrink.
This can happen if update_key needs to split a parent branch page.

6bd97d4286 ITS#8117 better fix 
Don't change mc_dbx because we would need to undo the change if
the txn aborts. Make the fix (for get) match existing code for put.

(Probably fixes the ITS, definitely fixes a bug) when collapsing
