pgsql: Replace pg_shadow and pg_group by new role-capable catalogs

Log Message:
-----------
Replace pg_shadow and pg_group by new role-capable catalogs pg_authid
and pg_auth_members. There are still many loose ends to finish in this
patch (no documentation, no regression tests, no pg_dump support for
instance). But I'm going to commit it now anyway so that Alvaro can
make some progress on shared dependencies. The catalog changes should
be pretty much done.
