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/.

This is helpful when the ar executable is named differently, for
example with an arch specific prefix.

After delete/add of a node, other nodes may no longer be
pointing at the data they intended. This can confuse subsequent
fixups.

Only set it if the cursor's current position was deleted

Based on page_touch fixup from ITS#7594 but expanded:
make sure sub-cursors agree with main cursors.

Always reinit mc_pg[0] if cursor is not C_INITIALIZED
It might have a stale value when using nested txns

Always unset C_INIT flag if the cursor's target DB has been deleted

Must remove our spilled pages from parent's dirty list

mdb_load -T was supposed to read escaped text, but 21b51cb7 "Add mdb_load"
made it read hex.

DUPFIXED fixups needed to occur after separator update.
MDB_RESERVE handling moved after split fixup.

In rebalance/split operations, temporary cursors need to be visible
to propagate fixups

Ignore sub-cursors that shouldn't be fixed up

Set a valid txn so that cursor fixup code works on the shadows

It was reporting spurious errors due to uninit'd cursors

Adjustments can't be skipped, in recursive calls each level must
fixup their own level.

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.

Just tell explicitly which direction we moved/merged from

Deleting the merged page requires bumping down other ki's
of the page's parent.

Keep dirty_room sync'd with dirty_list

dummy flags must be init'd due to 3d46d550

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