state->cli->dc does not have to be set (e.g. when running
net rpc join against an older Samba PDC), so check it before dereferencing it
This fixes Bug 9669 - net rpc join crashes against a Samba 3.0.33 PDC

Since we open with dbwrap, it auto-converts old tdbs (which it will
rename to secrets.tdb.bak once it's done).

For simplicity, we use this in the caller to choose between filenames.

This is another belt-and-braces check in case someone decides to turn
on the fancy new .ntdb extension, and we haven't converted it to ntdb.

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 next patch make dbwrap_local_open() call the ntdb backend for ntdb
files, but we don't want to add ntdb support to the old autoconf
build. It's cleaner to use the existing DISABLE_NTDB flag rather than
test for _SAMBA_BUILD_ in dbwrap_local_open.c.

This is a dbwrap backend for ntdb. It's a fairly straight conversion from
the tdb version.

ntdb's transaction code has an optimization which tdb's doesnt: it
only writes the parts of blocks whose contents have changed. This
means we can actually have a transaction which turns out to need no
recovery region.
This breaks the recovery setup logic, which sets the current recovery
size to 0 if there's no recovery area, and assumes that we'll always
create a new recovery area since the recovery will always need > 0
bytes.
In fact, if we really haven't changed anything, we can skip the
transaction commit altogether: since this happens at least once with
Samba, it's worth doing.
