Support SECURITY LABEL on databases, tablespaces, and roles.

Browse Source 
This requires a new shared catalog, pg_shseclabel.

Along the way, fix the security_label regression tests so that they
don't monkey with the labels of any pre-existing objects.  This is
unlikely to matter in practice, since only the label for the "dummy"
provider was being manipulated.  But this way still seems cleaner.

KaiGai Kohei, with fairly extensive hacking by me.
