2a6bfa56f0 mdbx: backport - more for cursor tracking. 
Includes:

 - ITS#8321 deinit empty cursors
   Always unset C_INIT flag if the cursor's target DB has been deleted

 - ITS#8321 Fix mdb_cursor_set
   Always reinit mc_pg[0] if cursor is not C_INITIALIZED
   It might have a stale value when using nested txns

 - ITS#8321 mdb_put cursor needs tracking too

 - ITS#8321 page_touch - don't fixup the cursor we just touched

 - ITS#8321 More cursor fixup
   Based on page_touch fixup from ITS#7594 but expanded:
   make sure sub-cursors agree with main cursors.

 - ITS#8321 cleanup unused var

Change-Id: I4b825e20e9d42d3166052e9b3e5bd0ac33b70e85

ITS#8321 fix ambiguity in cursor_put fixup

After delete/add of a node, other nodes may no longer be
pointing at the data they intended. This can confuse subsequent
fixups.

aeea7ebb08 mdbx: backport - ITS#8321 a lot for cursor tracking. 
Multiple bugs were fixed in the cursor fixups which
adjust other open cursors in response to various write ops.

Includes:

 - ITS#8321 Fix del/dupsort.
   When deleting a dupsort key, if other cursors pointed at that key,
   set them to uninit'd, not EOF. They no longer have anything to
   point at.

 - ITS#8321 don't skip fixups on splitting cursors.
   Adjustments can't be skipped, in recursive calls each level must
   fixup their own level.

 - ITS#8321 fix mdb_cursor_chk().
   It was reporting spurious errors due to uninit'd cursors

 - ITS#8321 fix mdb_cursor_shadow().
   Set a valid txn so that cursor fixup code works on the shadows

 - ITS#8321 fix mdb_cursor_put.
   Ignore sub-cursors that shouldn't be fixed up

 - ITS#8321 track temporary cursors.
   In rebalance/split operations, temporary cursors need to be visible
   to propagate fixups

 - ITS#8321 simplify page_split fixups.

 - ITS#8321 reorganize page_split fixups.
   DUPFIXED fixups needed to occur after separator update.
   MDB_RESERVE handling moved after split fixup.
