We delete and add of records rebalace the tree, but our
traverse code doesn't handle that and skips records
randomly.
We maintain records in a linked list for now
in addition to the rbtree and use that list during
traverse.
This add a bit overhead, but at least it works reliable.
If someone finds a way to do reliable traverse with the
rebalanced tree, we can replace this commit.

Multiple dbwrap_traverse_read() calls are possible.
store() and delete() on a fetch locked record
are rejected during dbwrap_traverse_read().
A dbwrap_traverse() within a dbwrap_traverse_read()
behaves like a dbwrap_traverse_read().
Nested dbwrap_traverse() calls are not possible.

We want to know (by crashing) when we free the database with records still
around. This would be a serious violation of our data structure hierarchies.

This is currently not strictly necessay, because the
only caller catches the DBWRAP_LOCK_ORDER_NONE case,
and maximum is already checked, but this seems too dangerous to me.
Use the new DBWRAP_LOCK_ORDER_VALID() macro.

Ther are still some databases which are opened (locally) with
lock oder 0, which means don't do lock oder checking,
thereby circumventing this deadlock-prevention mechanism.
Add a symbolic constant for this "0" to make this circumvention
more explicit.
