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.

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.

This provides an extra safety check that everyone is using one or the
other: you can't create a tdb file if there's an ntdb file.

This switches dbwrap_local_open() based on the extension of the
database name, so it handles both TDB and NTDB files.
Moreover, if asked to open a .ntdb, and there's no ntdb file but
there's a .tdb file, it converts that then moves it to .tdb.bak before
opening, and turn the .tdb file into a dangling symlink to make sure
it's never accidentally re-created or used:
$ ls -l secrets.tdb
lrwxrwxrwx 1 rusty rusty 23 Feb 11 11:31 secrets.tdb -> This is now in an NTDB
This provides transparent upgrade if people decide to use NTDB on a
database. Downgrade would be manual, eg:
ntdbdump foo.ntdb | tdbrestore foo.tdb && mv foo.ntdb foo.ntdb.bak

The flags returned were TDB-specific: this was only used for detecting
the endianness of obsolete databases (the conversion code was put in in
2003, with reference to Samba 2.3).
It's easier to remove it than to translate the NTDB flags to TDB flags,
and it's a really weird thing to ask for anyway.
