A new wrapper tdb_validate_open() takes a filename an opens and closes
the tdb before and after calling tdb_validate() respectively.
winbindd_validata_cache_nobackup() now dynamically calls one of
the above functions depending on whether the cache tdb has already
been opened or not.

I had only tested with "net getlocalsid". posix_locking_init() calls this
with a NULL name...

This makes it possible to set the default hashsize for any tdb. I would
like to remove the "open files database hash size" in favor of this one.
I'll check that removal in with the next commit, please complain/revert
if it's not ok.

If restoring a backup fails due to lack of space, remove the
corrupt tdb previously moved away to "name.corrupt", and retry.
If restoring still fails, move the backup in place instead of
copying it.

- call tdb_validate on the given tdb.
- if validation is successful, create a backup
return 0 (success) even if the backup fails.
- if validation fails:
- move tdb to name.corrupt (don't exit if this fails)
- look for a valid backup
- if a valid backup is found, restore it, else return -1 (failure)
if restoring succeeds, return 0 (success), else -1 (failure)
Summing up:
If 0 is returned, there is a valid tdb at the given location:
either the original one ore one restrored from a backup.
If -1 is returned, there is no valid tdb at the given location:
Either there is no file at all, or the original file is still
in place (if moving it away failed).

functions did not do so but returned an error. (This is the case when
error occurred deeper than at the level of the content checking done by
the per entry validate_fn.)

This is a wrapper around tdb_validate, that does backup handling:
* if the given tdb is valid, a backup is created (name.bak)
* if the tdb is invalid, if a valid bakup is found (validated
with the same validation function) under the name "name.bak"
the orignal tdb is moved to name.corrupt and the backup
is restored.
For the backup handling, a variant of the backup_tdb function
from lib/tdb/tools/tdbbackup.c is included in lib/util_tdb.c.
The copy function for the traverse action eliminates the need
to maintain a global success state by using a struct wrapping
the target tdb and a success flag as the private data.

from the validating child process down to the parent though the
pipe. All the parent evaluates is the overall success, so the exit
status should do.

Next, there will be a backup handling for the tdb files.
