r11567: Ldb API change patch.

This patch changes the way lsb_search is called and the meaning of the returned integer.
The last argument of ldb_search is changed from struct ldb_message to struct ldb_result
which contains a pointer to a struct ldb_message list and a count of the number of messages.
The return is not the count of messages anymore but instead it is an ldb error value.

I tryed to keep the patch as tiny as possible bu as you can guess I had to change a good
amount of places. I also tried to double check all my changes being sure that the calling
functions would still behave as before. But this patch is big enough that I fear some bug
may have been introduced anyway even if it passes the test suite. So if you are currently
working on any file being touched please give it a deep look and blame me for any error.

Simo.
