af45cf3a04 ITS#8300 fix rebalance after node_move 
ITS#8258, ITS#7829 fixes checked parent index to see if we were moving
from a left neighbor. Should have just checked to see if current index
was 0, meaning we added on the left. (Parent index may not tell us
anything meaningful after a nested rebalance.)

c62b77b661 ITS#8299 fix page_merge cursor fixup 
The parent's mc_ki has changed. We need to fix that up as well
in other cursors.

01342bd5d2 ITS#7377 Always notice env error on txn startup. 
Move the check to the end of txn startup.  Catches env
breakage which happens while the new txn waits for a lock.

a3ae2e7db1 Catch most uses of finished/parent txns. 
* Add MDB_TXN_FINISHED, MDB_TXN_HAS_CHILD, MDB_TXN_BLOCKED.
* Clear mt_numdbs in writers, for TXN_DBI_EXIST() to catch.
  We already do in readers.

9266843fa6 Move code into mdb_txn_end(). Was mdb_txn_reset0. 
Side effects:
* Clean txn up a bit even before freeing it.
* Tweak DEBUG output at txn end. Add DEBUG after commit(writer).

3f6fa7aece Set/clear mp_pad, md_pad (MDB_DUPFIXED data size). 
mdb_xcursor_init1(): md_pad is only used when MDB_DUPFIXED.
mdb_page_split():    Copy mp_pad too. Used by mdb_page_list().

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.

The tree height can also increase during rebalance, not just shrink.
This can happen if update_key needs to split a parent branch page.
