Merge branch 'bridge-mcast-tmp-router-port'

Nikolay Aleksandrov says:

====================
bridge: mcast: add support for temp router port

This set adds support for temporary router port which doesn't depend only
on the incoming queries. It can be refreshed by setting multicast_router to
the same value (3). The first two patches are minor changes that prepare
the code for the third which adds this new type of router port.
In order to be able to dump its information the mdb router port format
is changed in patch 04 and extended similar to how mdb entries format was
done recently.
The related iproute2 changes will be posted if this is accepted.

v2: set val first and adjust router type later in patch 01, patch 03 was
split in 2
