Add an alternative path involving VLAN 777 instead of the current 555. Then
add tests that verify that marking 777 as PVID makes the 555 path not work,
and the 777 path work.

When everything is configured, VLAN membership on the bridge in this
selftest are as follows:
# bridge vlan show
port vlan-id
swp2 1 PVID Egress Untagged
555
br1 1 Egress Untagged
555 PVID Egress Untagged
Note that it is possible for untagged traffic to just flow through as VLAN
1, instead of using VLAN 555 as intended by the test. This configuration
seems too close to "works by accident", and it would be better to just shut
out VLAN 1 altogether.
To that end, configure vlan_default_pvid of 0:
# bridge vlan show
port vlan-id
swp2 555
br1 555 PVID Egress Untagged

Add a topology diagram to this selftest to make the configuration easier to
understand.

When creating the second host in h2_create(), two addresses are assigned
to the interface, but only one is deleted. When running the test twice
in a row the following error is observed:
$ ./router_bridge_vlan.sh
TEST: ping [ OK ]
TEST: ping6 [ OK ]
TEST: vlan [ OK ]
$ ./router_bridge_vlan.sh
RTNETLINK answers: File exists
TEST: ping [ OK ]
TEST: ping6 [ OK ]
TEST: vlan [ OK ]
Fix this by deleting the address during cleanup.

Add test for cases where bridge itself acts as a router interface, with
front panel port attached to the bridge in question.
In the first test (router_bridge.sh), VLAN memberships are not
configured in any way, and everything uses default PVID of 1. Thus
traffic in $h1 and $h2 is untagged. This test ensures that the previous
patches didn't break a currently working scenario.
In the second test (router_bridge_vlan.sh), a VLAN 555 pvid untagged is
added to the bridge CPU port, with that VLAN leaving the bridge tagged
through its sole member port. The traffic is therefore expected to come
out tagged at $h1. This tests the fix introduced in the previous
patches.
