Let "illegal" branch pages thru on the FreeDB - the condition
is only temporary and will be fixed by the time rebalance finishes.

Avoid read txn-flags from shared write TXN (e.g. env->me_tnx0->mt_flags)
without holding a write-mutex.

The motivation for this change is my distribution moving to a multiarch
layout. While the architecture specific stuff (binaries, libraries,
etc.) is installed under /usr/${host}/{bin,lib,...} architecture-independent
data should still be installed to /usr/share/.

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

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.

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.

Check for top of stack. Usually the cursor only has height 1 when
calling page_split, but not always.

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.
