d23a3f3bc4 mdbx: drop inherited broken audit. 
Internal self-audit (inherited from LMDB) is invalid and useless
for sub-db and dupsort cases.

9baca673ac mdbx: backport - XCURSOR_REFRESH() fixups/cleanup. 
* Check NUMKEYS(), similar to f34b61f9471d1c03fe0517b9d817c50c920e378a
  "ITS#8722 fix FIRST_DUP/LAST_DUP cursor bounds check".
* Move XCURSOR_INITED() into XCURSOR_REFRESH().  This adds a check in
  mdb_cursor_put, below /* converted, write the original data first */.
* Factor mc_ki[] out to XCURSOR_REFRESH().
* Replace an mc_pg[] with mp which is equal (mdb_cursor_del0).

* This checks XCURSOR_INITED() and fixes the mn_flags check.

97e1d9b685 mdbx: fix mdb_cursor_last (ITS#8557). 
This is a port of http://www.openldap.org/devel/gitweb.cgi?p=openldap.git;a=commit;h=d84dee516fa4cca41b5234e95c2105eb4737dfb3

HYC: Optimize mdb_page_search_root(PS_LAST) when cursor is already
     near last position, ignoring C_EOF flag for now.

LY: Fixed C_EOF check. Don't ignore it, otherwise in some cases
    we got a "MDB_PAGE_NOTFOUND", instead of just "MDB_NOTFOUND".

9c02fad4cd mdbx: support glibc < 2.18 for TLS cleanup on thread termination. 
One more for https://github.com/ReOpen/ReOpenLDAP/issues/48
against https://sourceware.org/bugzilla/show_bug.cgi?id=21031
and https://sourceware.org/bugzilla/show_bug.cgi?id=21032

It is impossible to completely fix this issue for glibc prior to 2.18,
in such case this fix just minimizes the probability of a crash.

02de457f3c mdbx: more rework TLS cleanup on thread termination. 
One more re-fix https://github.com/ReOpen/ReOpenLDAP/issues/48
Here is only part of the work for glibc >= 2.18

--

Unfortunately, the two bugs related to pthread_key_delete()
are present in all glibc versions:

1) The race condition between pthread_key_delete() and thread's
finalization path, from where a TSD-destructors are called.
Therefore some TSD-destructor(s) could be executed after that
the pthread_key_delete() was competed.

2) ld.so infrastructure does not tracks a TDS-destructors.
Therefore a lib.so could be unloaded while corresponding a
TSD-destructor(s) were even not completed or still were not called.
