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.
