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.

ef00ee6095 mdbx: backport - Doxygen fixes. Use DISTRIBUTE_GROUP_DOC. 
- DISTRIBUTE_GROUP_DOC makes doxygen give several fields the
  same doc: mn_hi + mn_lo in MDB_node.
- Don't hide a doxygen #name inside double quotes.

fca2f4d929 mdbx: backport - clean up and comment C_UNTRACK. 
Don't use it as a "cursor is tracked" hint in mdb_pages_xkeep().
It's been harmless so far, but would break after mdb_cursor_copy().
Checking m0 directly short-circuits better anyway.
