Restore netdomain allow rules. Change I4be1c987a5d69ac784a56d42fc2c9063c402de11 removed all netdomain allow rules at the same time domains were made unconfined. Prior to that change, any domain that used the net_domain() macro would be granted permissions required to use the network via these rules. The change made the netdomain attribute unused in any rules, thereby rendering the net_domain() calls pointless and requiring the allow rules to be duplicated for any domain requiring network access. There are two ways to resolve this inconsistency: 1. Restore the netdomain rules as in this change. In that case, some rules in app.te can be removed as they are redundant with these rules. -or- 2. Completely remove the netdomain attribute, the net_domain() macro, and all calls to it. In that case, each domain that requires network access will need to duplicate these rules or the necessary subset in order to function.
