5d4a23138c mdbx: backport - ITS#8320 mdb_load: fix loading data from simple text files. 
mdb_load -T was supposed to read escaped text,
but 21b51cb7 "Add mdb_load" made it read hex.

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.

This fix a TLS-memleak for thread from which mdbx_env_close_ex()
has been called. Bug was added by while fixing the
https://github.com/ReOpen/ReOpenLDAP/issues/48

In general we should explicitly free(), because
pthread_key_delete() don't calls a destructor.

ee26517b5d mdbx: backpost - 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.)

Includes:

 - ITS#8300 fix node_move
   Don't adjust other cursors when we added a node on the right.

 - ITS#8300 more for node_move fixups
   When moving a node from the right neighbor, a different
   adjustment is needed.

 - ITS#8300 simplify

 - ITS#8300 more for node_move
   When moving a node from one page to another, make sure other cursors'
   parent index gets adjusted too.
