switch dbus ranged calls from daemon domain to system domain. This works
around a type transition conflict. It is also why the non-ranged
init_system_domain() is used instead of init_daemon_domain().
A recent update added an generic context for the lock files, so the
entry in distro_redhat can be removed.

The attached patch allows unprivileged clients to export from or import
to the largeobject owned by themselves.
The current security policy does not allow them to import/export any
largeobjects without any clear reason.
NOTE: Export of the largeobject means that it dumps whole of the
largeobject into a local file, so SE-PostgreSQL checks both of
db_blob:{read export} on the largeobject and file:{write} on the
local file. Import is a reversal behavior.

The attached patch fixes incorrect behavior in sepgsql_enable_users_ddl.
The current policy allows users/unprivs to run ALTER TABLE statement
unconditionally, because db_table/db_column:{setattr} is allowed outside
of the boolean. It should be moved to conditional section.
In addition, they are also allowed to db_procedure:{create drop setattr}
for xxxx_sepgsql_proc_exec_t, but it means we allows them to create, drop
or alter definition of the functions unconditionally. So, it also should
be moved to conditional section.
The postgresql.te allows sepgsql_client_type to modify sepgsql_table_t
and sepgsql_sysobj_t when sepgsql_enable_users_ddl is enabled, but
it should not be allowed.

OK, the attached patch adds the following types for unprivileged clients.
- unpriv_sepgsql_table_t
- unpriv_sepgsql_sysobj_t
- unpriv_sepgsql_proc_exec_t
- unpriv_sepgsql_blob_t
These types are the default for unprivileged and unprefixed domains,
such as httpd_t and others.
In addition, TYPE_TRANSITION rules are moved to outside of tunable
of the sepgsql_enable_users_ddl. IIRC, it was enclosed within the
tunable because UBAC domains (user_t and so on) were allowed to
create sepgsql_table_t, and its default was pointed to this type
when sepgsql_enable_users_ddl is disabled.
However, it has different meanings now, so the TYPE_TRANSITION rules
should be unconditional.
