r3005: added talloc wrappers around tdb_open() and ldb_connect(), so that the
caller doesn't have to worry about the constraint of only opening a database a single time in a process. These wrappers will ensure that only a single open is done, and will auto-close when the last instance is gone. When you are finished with a database pointer, use talloc_free() to close it. note that this code does not take account of the threads process model, and does not yet take account of symlinks or hard links to tdb files. (This used to be commit 04e1171996612ddb15f84134cadded68f0d173b2)
