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.
