correctly. For the clustering case.
Clustered setups should have only ever used
the unsigned version of TDB_DATA in the
first place so they can't be in this mess :-).
Just do the normal upgrade in the clustered case.

The _bystring function are now just tiny wrappers.

This backend can be used untill ctdb knows about real
transactions.
It stores a master tdb in a shared location and a readonly copy
on the local harddisk. Reads are always on the local tdb
and writes always on both. Change notify messages are send
to all message context, which ask for them. With the notifies
it's possible to just update the changed records, instead of
copying all records (which is the fallback).
You need to configure:
dbwrap:use_tdb2=yes
dbwrap_tdb2:master directory=/some/shared/path
dbwrap_tdb2:local directory=/var/lib/samba

This should be used when transactions are wanted.
For now it's just a wrapper of db_open(), but this
will change.

Stick to hand-written headers (that are there anyways).
Add some missing prototypes to util_tdb.h and dbwrap.h.
I did not bother to add a header for each single dbwrap backend
open function but put the prototypes for the open functions into
the central dbwrap.h.

Only filled in for tdb so far, for rbt it's pointless, and ctdb itself needs to
be extended

different
database backends in place dynamically.
The main abstractions are db_context and db_record, it should be mainly
self-describing, see include/dbwrap.h. You open the db just as you would open
a tdb, this time with db_open(). If you want to fetch a record, just do the
db->fetch() call, if you want to do operations on it, you need to get it with
fetch_locked().
I added dbwrap_file.c (not heavily tested lately) as an example for what can
be done with that abstraction, uses a file per key. So if anybody is willing
to shape that up, we might have a chance on reiserfs again.... :-)
This abstraction works fine for brlock.tdb, locking.tdb, connections.tdb and
sessionid.tdb. It should work fine for the others as well, I just did not yet
get around to convert them.
If nobody loudly screams NO, then I will import the code that uses this soon.
