====================
net: bridge: vlan: add global mcast options

This is the first follow-up set after the support for per-vlan multicast
contexts which extends global vlan options to support bridge's multicast
config per-vlan, it enables user-space to change and dump the already
existing bridge vlan multicast context options. The global option patches
(01 - 09 and 12-13) follow a similar pattern of changing current mcast
functions to take multicast context instead of a port/bridge directly.
Option equality checks have been added for dumping vlan range compression.
The last 2 patches extend the mcast router dump support so it can be
re-used when dumping vlan config.

patches 01 - 09: add support for various mcast options
patches 10 - 11: prepare for per-vlan querier control
patches 12 - 13: add support for querier control and router control
patches 14 - 15: add support for dumping per-vlan router ports

Next patch-sets:
 - per-port/vlan router option config
 - iproute2 support for all new vlan options
 - selftests
