route/vlan: allow clearing vlan ingress map
An entry of the ingress map can be cleared by setting
the "to" part to zero.
Previously, vlan_put_attrs() would skip over zero "to"
and thus the user cannot unset an ingress map entry.
Add a modified-mask to record the state of each ingress
map entry and also sent explicit zeros to kernel.
when we receive a IFLA_VLAN_INGRESS_QOS message from kernel,
vlan_parse() similarly sets the received entries as modified.
This preserves previous behavior when using a received object
to modify a vlan.
Add a capability NL_CAPABILITY_RTNL_LINK_VLAN_INGRESS_MAP_CLEAR
to indicate the behavioral change.
